cerobit KTJ LCD Digital Thermometer Hygrometer Temperature Humidity Meter with 1m Sensor Wire

This is an excellent tool - exactly what I was looking for (although Fahrenheit readout would be nice - - the simple conversion is: Celsius x 2 minus 10% and add 32, so 10 Celsius = 10x2 is 20, then subtract 10% (20-2)=18, and Add 32 ... 50 degrees F = 10 degrees C. It's easier than 9/5*C+32 for mental math. I have found it tends to read about 1.7 degrees high (C). I referenced it to 4 other thermometers at temperatures ranging from about 0 to 18 C. It was pretty consistent across the range.If it was more accurate and had a Fahrenheit readout, it would have gotten 5 stars.

Drawback is I didnt know it only reads in C and not F ... I use this in my ball python tank so temp. and humidity is important so I just went on google and got a C. chart and printed it for the temps .. other than that no big deal it works great

Seems to work fine monitoring my humidor. The only thing to note is the temperature reading is C°.

It wouldnt let me put 0. This thing dont work and there is no way to replace battery
