Review on PEMENOL Fahrenheit Temperature 76F 999F Thermocouple by Jose Wititsuwannakul

I wanted a dual readout thermometer that uses two sensors to measure the flow and return temperatures in my heating system. Unfortunately, only one of the sensors can be removed, the other is in the housing and converting to a second external sensor is impractical. Other than that, it seems to be working fine. I was able to get DC power with a single diode from a 28V AC transformer in a heating system and had no issues with pulsing DC power.
