    Perfect acurate readings so far a bit hard to change from celcius to Fahrenheit

    Does what it’s supposed to
    I’ve stood and watched it fluctuate in temps when my tank heater is both in “active heating mode” (red light on) and at standby “preset temp,” (green light) so this digital thermometer is doing exactly what it’s supposed to (unlike those worthless stick-on-tank types)Happy with purchase

    Easy to use
    Purchased 2 of these to use for my reptile incubator boxes. They were easy to use and read without effort. One of them kept going in and out and stopped working shortly after. They are cheap enough so I wasn’t worried. I’ll probably purchase a few more.

    Very Inaccurate
    Off by a full 2-3 degrees on any given day. Have confirmed with multiple other probes and thermometers. Very disappointed and you need the original package to return. Save your money.

    Battery (common LR44 size) last a very long time in this thermometer/humidistat
    I use this in my car in both summer and winter and leave it on all the time the battery last the whole 4 seasons on the east coast and even longer. Mostly I bought this for the summer to check the air conditioners output as it is very accurate. Once the A/C starts putting out 50F on a 75F day then I know I need to install a can a R134a to bring it back to spec. Plus its always nice to know exactly how cold or hot the air is coming out of the vents IMHO and this kit serves this purpose very well. I would imagine its just as useful as an aquarium or terrarium thermometer/hydrometers in the same way. This device has a multi use and multipurpose usages. Highly recommended, buy two they are cheap enough and most times come in a deal package with two already included. Again, low drain on battery means a new battery may last a year, year and and a half, no problem and that is a great feature in an of itself.

    Simple Way To Monitor Temperatures, In A Wide Variety Of Situations
    I requested this item to test the effectiveness of the different insulated bags that I use while delivering food. It is important to determine which piece of delivery equipment works best in keeping hot food hot and cold food cold. Additionally, new laws could be coming that will hold food delivery drivers to a higher standard, which I agree with. Therefore, it is important to know which item keeps things the hottest and the coldest. Every degree matters.Upon receiving the item, I tested it using food I purchased for myself. First, I set the thermometer in the bag to test the ambient temperature, and then I observed how the temperature changed while hot or cold food was inside. Next, I used the probe and set it inside a cold “slushy” drink and a hot “coffee” drink. Although some people might say that this isn’t completely accurate, I believe it gives a good idea of how the temperature varies due to the minimum and maximum temperature values. I was less concerned with it showing a 100% accurate temperature than with seeing which pieces of equipment “appeared” to be more effective at keeping things hotter and colder. I used this information to determine which equipment I should use when picking up a customer’s order.This way, if the law gets updated and/or passes, I will already have a decent idea of the temperature range of each item and, if needed, can obtain more advanced temperature monitoring equipment. If you are like me and just looking for a basic thermometer that can display the minimum and maximum temperature in both degrees Fahrenheit and Celsius, which allows you to measure temperatures in multiple ways that are cheap, then this item might be right for you. However, if you are looking for a thermometer that is the most accurate and heavy-duty, then this item might not be for you. Overall, for the price, this item is well worth purchasing due to the wide variety of options you get when measuring temperatures, especially having a minimum and maximum temperature display.

    今の所、正常に水温示してます。いい感じです。ただ、本体のボタンは写真は黄色ですが実際はオレンジです。

    この水温計を3個購入しました。外気温でTANITAの温度計と比較して±0.2の範囲でした。(TANITAの温度計どうしでも±0.1の差がありました)水中では、エヴァリスきっちり計れる水温計(アナログ)と比較してほぼ一致します。精度、価格ともおすすめの水温系です。
