Digital Thermometer with External Sensor, Magnet, Suction Cup, Water Thermometer, Aquarium, Refrigerator, Freezer (White)

This little device will save your food in your freezer during a power outage. Put the sensor near the top and when the temp gets 20 degrees Fahrenheit, you better start the generator or plug the power station in and pull the temp. back to 5 degrees or so. Saves having to open up the freezer to check food on top for thawing. Has a strong magnet that sticks well to the side of the freezer, easy to read numbers.

Works great to monitor the temp of my shower and bath for cold plunges. Heads up your tap water is not as cold as one might think!

Pros:- Temperature readings match calibrated thermapen within thermapen's tolerance.- Uses regular easy to find and cheap AAA batteries. This is reason alone to buy it as coin cells quickly cost more than the unit!- Display is large/clear enough for old eyes to see across the room.- Feature (min/max) work as expected- Works well as a remote sensor for aquariums, greenhouses, and outside air hanging out a window.Cons- Thick cable leaks cold from upright fridge/freezer. Put sensitive part of face up to cable passing under door seal, and you'll feel significant cold air draft if your fridge/freezer has a circulation fan. While the freezer might keep up, its significantly increasing energy consumption and shortening the compressor life. Use in a chest freezer (without forced fan) seems to leak much less cold air. There is also no frost buildup right around cable inside the freezer indicating little air leak.- No alarms. A high or low alarm would be desired if a fridge/freezer is too warm, or a greenhouse/aquarium is too cold.

Works great on my brooders, have bought four of them. The magnetic on back makes it great to hold in place on each brooder. The only down side is from time to time it change to centigrade reading.

works great.

We ordered the HATUSOKU Digital Thermometer believing that the product was manufactured in Japan. I also expected that with a MIN/MAX feature, those values could be set by consumer. WRONG on both accounts. The MIN/MAX feature of this product appears to be that it is a preset internal calculation that relies on the current measured temperature. What good is that? To what purpose is it to see arbitrary values displayed that have no relevance? More importantly, the included literature is concise as far as manipulating the device but inaccurate in that the MIN/MAX option is dependent upon the probe's currently recorded temperature & a predetermined calculation. I can find NO option for setting the MIN/MAX values manually and I might just want more than a 3-to-4 degree range between minimum and maximum temperatures. So, what did I get for my money? I basically received a temperature probe attached by cable to an external digital display head that can display either English or Metric temperature scale readings. The probe cable is run between the door sealant strips but can allow cold air to escape. The loss of cold air from a sealed system increases operational costs while diminishing efficiency of the operation. The electronics can add and subtract a couple of degrees from recorded temp & display those calculations as a "minimum" and "maximum" value, but, again, where and what is the relevance of those calculated values? I mean, unless the product has an alarm mechanism that initiates when the temp exceeds either the MIN or MAX value, the feature is pointless, right? Oh well, at least it gives me a relatively accurate temperature reading. Three stars for functioning correctly as a thermometer.

Works wonderful very easy to hook up

Garbage! doesn't read correct, killed a battery in a couple months, NOT WATER PROOF.You get what you pay for.
