Apera Instruments PH60-WW Handheld pH Meter Tester Kit with LabSen 335 ATC pH Electrode for Lab-Grade pH Measurement in Wastewater, Suspensions, and Emulsions

Accurate, works well, calibration tools all included. Need to supply your own DI/distilled water but otherwise great

I wanted to check the accuracy of the pH sensor our pool had. I also hate using those tester strips which require identifying if the colour is light yellow or pale amber... I mean, really? Plus those strips are calibrated for a specific temperature, so any result you get with them will likely be wrong if your water temp is outside the norm. Anyhow, I hunted around and this seemed to be the one a lot of people recommended. It came in a neat little kit that included everything you needed in a hard shell case - although I'd recommend also buying some extra storage solution as the included amount will not last long. Use is super easy, and it automatically adjusts for temperature. You can also modify the settings so the backlight changes colour if the reading is outside the ideal numbers. I wondered why the case had an empty spot, then I realised that was so you could stand the tester up with the cap filled with storage solution. A really nice touch. If you want to keep it in the case with the lid closed, you just need to remember to store it on the side so there is less chance of leakage from the cap. Keep in mind that if you store it in tap, pool, or distilled water that could damage and permanently impact the accuracy of the tester. They do say that if it is stored dry, then that will also impact the accuracy of the sensor, but this can be fixed by soaking it in storage solution for a few days. Personally, I'd just get the storage solution - it's not expensive, the cap only requires a small amount, and you don't have to replace it after every use so a bottle will last a while. As for accuracy - I don't have a lab quality reference device to test it against, but it definitely appears to be more than accurate enough at least for testing a pool at home. I can't say anything about longevity as I've only had it now for a few weeks, but the sensor is replaceable plus it appears to be well made - so I think it should last well if treated with the care something like this deserves. They do have a newer version of this that has bluetooth and a "new improved sensor". For me this is more than good enough I think, I don't really have any need to track the readings over time, and as much as I am a geek the additional cost didn't really seem to justify it. Overall, very happy with this tester.

Bough the pH tester for use in making probiotics fermented fruit juice. The included instructions were detailed & clear and calibrating the device before first use with the included calibration solutions was quick & easy. The device is easy to use and well made. Would highly recommend it anyone who is serious about testing food samples quickly & accurately.

Apera makes a good PH60 pH probe that has a nice display, good accuracy and good repeatability. Kit comes with calibration standards for 4.00, 7.00 and 10.01 pH as well as some KCl probe storage solution so you can use it right away. Overfill the storage cap a bit to keep probe tip covered when storing probe horizontally. This probe seems to work fine on 4 x AAA NiMH rechargeable batteries.

I've had this meter for about 3 months. It's a high quality pH pen that's mostly easy to use and read. The calibration process is *relatively* easy. Get in calibration mode, set in the pH 7 solution, wait for the check mark, then do the same with the 4 & 10.01. Once you have it calibrated, use is easy. I notice that the design of the tip allows air bubbles to get stuck, which can be frustrating when you're trying to get an accurate reading. I'm unsure if it affects the reading negatively at all. When I try to shake the bubbles out, I notice that sometimes the battery connection stops working for a moment, then I have to turn the meter back on. That happens somewhat regularly. I'm a bit disappointed that a $70 pen has finicky battery terminal integrity, but if you're careful with it you won't have the issue. I wish I bought the pH & TDS combo meter, but in the meantime this one works well. I would recommend it.

Seems to me be accurate and is a great price point. Easy to calibrate as well

I use this as my back up PH meter, it is easy to calibrate and do3s the job

Nicely made and super easy to use, but find that it often can take several minutes to settle on a stable reading. Even when it comes up as stable, it will sometimes start changing again after 10-20 more seconds. Waiting on this probably isnt super important if you are shooting for just a semi-tight range and not a super precise exact value. Also found that every time I go to use it (lets say once a week at this point) when I check it against the calibration solutions, it's a little off and I have to recalibrate it each time. Hoping maybe there is a 'break in' period with the probe or something and that it will eventually hold calibration for longer. The way the tip of the probe section is (the plastic around it) it seems to often trap an air bubble inside it and can be a little tricky to shake the bubble out without just introducing a new bubble inside it. The timer for the backlight is pretty short but you can set it to always on instead in the options, would be nice if you could keep it on a timer but set it to longer so its not constantly turning off on you. The storage cap does not snap on, just press fit around a little gasket. It seems to always want to pop off ever so slightly, so when its laying down in the case sometimes the 3M KCL storage solution will leak out of it. Also seems you need to fill it slightly past the 'fill' line so that when its laying on its side the probe is completely covered. And speaking of the KCL, it comes with the tiniest amount so you'll probably want to pick up some more (which is common thing said in most of these reviews). It comes with a generous amount of the calibration solutions, but with the 3 vials for using during calibration, be careful with the tops. They need quite a decent amount of force (till you hear/feel a hard 'snap') to close otherwise they also will leak out into the case while they are on their sides. Then they are also a bit difficult to get the tops back off, they dont just pop off with ease, you have to force them off and I always feel like I'm going to spill them all over with how much force it takes to open them back up. The case itself is quite nice. The plastic does not feel cheap at all and the latches are nice and secure, except I do wonder if the thin plastic joint where the latches attach to the case will last after a while of them bending back and forth from opening and closing them. Inside the foam seems high quality and solid with the appropriate cutouts for each thing. The instuctions are very well done and simple to understand and follow. Overall this is a massive upgrade from the cheap test strips or testing drops etc. Not having to match up very slight differences in color shades and guessing which is close (especially if you're not testing something that starts off clear, such as a water/nutrient mix). Granted it's also a lot more expensive then those options as well, but the quality of it gives me the impression that it will last for a while (and with the replaceable probe, that should increase the lifespan though I will admit I have not looked at what a new probe would cost). Don't bother with the cheap digital testers that amazon is flooded with, go with quality from the start and you'll be much happier in the long run.

Vorweg: Das PH60 ist zu billig. Wenn man sich die meisten der negativen Rezensionen hier anschaut, weiß man, daß viele nicht in der Lage sind, mehr als einen Halbsatz in einer Bedienungsanleitung zu lesen. Für solche Leute gibt es doch Streifen- und Tröpfchentests, sie sollten dabei bleiben. Das reicht für die völlig aus. Ja, in der Abdeckkappe über der Sonde sind Feuchtigkeitsreste. Ja, das Gerät ist trotzdem neu und unbenutzt. Wie kommt's? Weil die Sonde feucht bleiben muß, wenn man sie sofort verwenden können will. Man kann die Glaselektrode auch trocken lagern, müßte sie dann aber vor der nächsten Messung 12 Stunden in Kaliumchloridlösung einweichen. Was sicher wieder etliche nicht lesen und folglich auch nicht beachten würden, nur um dann anschließend herumzuheulen, warum die Meßergebnisse nichts taugen ... Kopf -> Tisch Eine 1 vor den gegenwärtigen Preis würde das Problem vielleicht etwas lindern. Du liebe Güte. Zu meiner Bewertung: Das Gerät ist erstklassig und hochpräzise, hat aber Tücken: 1. Das Smiley im Display als Anzeige dafür, daß sich der Meßwert nun eingependelt habe, kommt zu früh. Insbesondere bei Flüssigkeiten mit einem relativ niedrigen Leitwert (unterhalb von 200 µS/cm etwa) dauert es länger, bis man ein zuverlässiges Ergebnis bekommt. Dafür kann das Gerät nichts, das sind Chemie und Physik, die das bedingen, aber für ein verfrühtes Smiley kann das Gerät dann sehrwohl. In solchen Fällen bitte Geduld mitbringen und das Smiley ignorieren, was auch mal 3 Minuten warten bedeuten kann, bis sich das Meßergebnis tatsächlich eingependelt hat. Beispiel von einer Messung heute: Der Leitwert beträgt 129 µS/cm, der pH-Wert nach 5 Minuten ist 7,92 Das Smiley kam aber schon nach 30 Sekunden bei einem angezeigten pH-Wert von 7,49. Man muß halt warten, wenn es präzise sein soll. Und genau dazu hat man das PH60 ja gekauft. 2. Damit zusammenhängend: Das Gerät schaltet zu früh ab. Das ist nicht weiter tragisch, dann muß man es, während es noch in die Meßflüssigkeit eingetaucht ist, nochmal einschalten und eben noch eine Minute länger warten. Aber ärgerlich ist es trotzdem. Leider ist diese automatische Abschaltung nicht deaktivierbar. Allgemein noch der Hinweis: Vor und nach jeder Messung, vor und nach jeder Kalibrierung, bei einer 3-Punkt-Kalibrierung auch nach jedem Zwischenschritt, dann noch bevor man das Gerät zurück in die Kaliumchloridlösung stellt sowie nachdem man es aus dieser wieder entnommen hat, bitte *immer* die Sonde mit destilliertem Wasser spülen und anschließend mit der Hand trockenschütteln/trockenschleudern. Niemals die Glas-Elektrode mit einem Tuch oder ähnlichem abwischen. Wirklich niemals. Das ruiniert die Glaselektrode. Das Gerät zeigt dann zwar noch Meßergebnisse an, das sind dann aber nur noch unbrauchbare Schätzwerte. Also Finger weg von der Elektrode. Destilliertes Wasser ist nicht im Lieferumpfang enthalten. Man sollte welches daheim haben oder hier bei amazon mitbestellen. Ich habe mir gleich einen 5-Liter-Kanister geordert, da ich es auch noch für andere Wassertests benötige. Wer sich von dem Gerät eine Zeitersparnis erhofft, ist hier falsch. Momentan sind echte Schnelltests nur mit Teststreifen und Tröpfchentest, also Indikatortests, realisierbar. Was entsprechend deutliche Verluste in puncto Genauigkeit zur Folge hat. Die oben genannten Punkte führen zu keinem Sterneabzug von mir. Wäre der Preis höher, wäre ich da pingeliger, so aber geht das trotzdem in Ordnung. Volle Punktzahl und Kaufempfehlung.

Bon produit, un peu lent a stabiliser. j'ai change pour le PC60, pour a peine plus cher qui fait la conductimetrie egalement.

Prodotto eccellente. Professionale.

I was looking for a ph meter for brewing and wanted something a little more accurate than the cheap Hanna one and all the really cheap Amazon ones. After some research I found this one. It’s exactly what I needed as it was just over $100 which was what I was looking for (trying not to get excessive and buy the Milwaukee) The accuracy is to .02 which is enough for my homebrew for sure. It worked excellent for the first brew I’ve done with it! The big thing that got this 5 stars is its an all in one kit. Comes with 3 point calibration fluids, little cups for them, and the instructions are laminated and are great. If you’re looking for a homebrew ph meter this is the one to consider for sure if you’re on a budget
