Review on Intelligent Thermostat Temperature Controller AC110V 240V Test, Measure & Inspect by Allen Hart

The description says that it is rated for temperatures from 0 to 1200 degrees Celsius, but in fact it is rated for temperatures from 0 to 400 degrees Celsius. Also, the thermocouple was defective and open (as with an open circuit due to its tips not being properly crimped). Even after I solved this problem, it showed -50 degrees Celsius at room temperature. There was no way this device was working properly. I tried using offset to fix the temperature, but that didn't work either, and the temperature reading changed by 50 degrees every second. I am returning it for a full refund and no replacement.
