Review on PEMENOL Fahrenheit Temperature 76F 999F Thermocouple by Orlando Mohr

I have this thermometer to monitor the inside temperature in a guest room in my house as well as the outside temperature. It's nice to have it show up right in my house instead of relying on google or an app to get the outside temp and be able to double check how well my air conditioning is working throughout the house. I tested it with a few different power supplies I had lying around, a 5v USB, a 9v battery and a 12v power supply I had for another project and it worked each with no issues accepted. As I know I will have to get another one at some point as I would like to have a temporary display in my car and I feel that would be nice. The overall quality of the device is really good, there are no flaws in the plastic case, the circuit board looks great, it definitely fits everything I need from it. I would have no hesitation in suggesting this for any project that you need or that can use a dual temperature gauge!
