Our digital thermometer can be used to measure fluid temperatures via a Pressure-Temperature (PT) plug. On a geothermal heat pump, the differential temperature (delta-T) measured between the entering and leaving water/fluid connections is an important value which indicates that heat is being extracted from or rejected to the loop. Knowing the fluid flow rate, delta-T, and type and quantity of antifreeze allows you to calculate the heat of extraction or rejection. These values allow you to check whether the heat pump’s performance is within the manufacture’s specified range.
