capetsma Reptile Thermometer, Digital Thermometer Hygrometer for Reptile Terrarium, Temperature and Humidity Monitor in Acrylic and Glass Terrarium,Accurate – Easy to Read – No Messy Wires… (1 Pack)

Nice little thermometer with a hygrometer with 1 issue. The device is in a extremly humid enviorment, 75 to 85 percerent humidity. I dont know if this is the problem but the display gets very light and hard to see if the humidity gets any higher. This does not seem to be a permanent problem as if I let it dry out, the display is fine. The only issue beyond that is trying to find a battery. It’s a LR44 which I could not find anywhere local. Fortunlaty a Energizer A76 worked just fine. Just a note, when you put in the battery it will defalt to Celsius. There is a tiny hole in the back marked C/F that useing a probe you push in to get to Fahrenheit. All in all a nice small device for temp and humidty for the price.
