TK295PLUS

I bought one of these in tank Ph meters along with a different one that does the same, at the same time. This one was calberated properly when it arrived. The other one I to recalibrate. Placed them in the tanks and the other one wouldn't read the temp correctly from the get go. This one was spot on with temp and Ph. I have a hand Held Ph meter also that I test with and it matches this meters readings.. The other meter started messing up on day 5, it stopped working altogether within a week. I returned it and bought another of these meters. They have been working perfectly. Love that I can now easily test my Ph levels with a touch of a button. Also like that they work with batteries. Now if they could come up with an In tank Gh and Kh meter. My shrimp would be happy!

Item calibrated straight out of the box, no issues. Seems to be holding a steady PH and temperature two weeks after purchase, I have always kept the probe submerged in water to prevent it from degrading. I can't even complain so far since it's so cheap, I didn't want to invest straight into a BlueLab Guardian so this is a better alternative for just starting DWC. I'll keep this updated!

This monitor is ideal for the strict PH regimen I have to follow. It is very accurate and easy to operate. The directions are clear and it comes with the calibration materials. I was impressed. I use it at least 2 times a day to keep good PH levels. The temperatures I am not to worried about but it tells me that as well if needed. Very nice tool and would really recommend it to all at this price point.

Seller did not state this is better operated. Would not have bought this if I knew that. Also doesnt even read accurately, after calibration it reads down 1.5 from my other meters. Don't waste your money

So I only monitor PH and Temperature in my nutrient solution a few times a day so I thought why buy the expensive unit with the automatic pump to adjust the PH if I am away during feeding. I open the door, turn the unit on, look at my beautiful plants, look at the monitor, adjust if needed then turn it off and shut the door. Works perfect. No need to leave the unit on all the time if you are not sitting there monitoring the monitor all the time. The unit came with the PH sensor wet and was spot on with my hand held monitor. You won't regret this purchase as long as you understand it's purpose. Cheers my friends. Stay Lifted!!!

Seems to work pretty well. Issue with the equipment is there are no mounting suction cups for inside aquarium use. I get it it is not solely designed for aquarium use. Still anytime used for pH monitoring it will be inside some container.

The tester works as well as more expensive probes I have used. It is accurate and easy to use and calibrate

For those that have bought several Ph monitors in the past, you know that the price point for something built for longevity is over $100. Replacement double junction probes alone start at $60-$70, so walking into this I didn’t expect a lot. I ordered two and was impressed with the build quality of the unit. It’s solid and heavy, and actually feels in the hand to be a better build quality than other monitors for $80-$90 that come with a probe. The calibration was so easy I did it a few times because I thought I was doing something wrong (the unit self-senses the area it needs to calibrate to depending on the calibration fluid). One unit worked well and is still working well a couple of months later (with the original probe, but I plan to replace the original with a double junction probe down the line). The second unit appeared to short out when the temperature probe and the ph probe were I. The same water (I took out the temp probe, it read ph, I took out the ph probe, it read temp, I put both in, I got “——“. I contacted the company about the faulty unit and they had be do a few tests over a couple of days to determine what was happening with the unit. After a few days the company confirmed the unit as faulty and replaced the unit. The replacement I received I’ve been using for 3-4 weeks now and no issues whatsoever. Remember, you get what you pay for, and I’ve not seen too many places that sell a unit with a probe for this price. I’m very pleased with the purchase.
