Unit powers on and passed all basic function checks. 

The Duniway Stockroom Corp. Digital Thermocouple uses the thermal conductivity property of gases, by incorporating a wire filament which is heated by a constant source of power. Attached to this filament is a thermocouple, which measures the temperature of the wire. At high pressures, the large number of gas molecules striking the heated wire carries energy away and cools the wire.
