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.
A digital thermocouple thermometer, also known as pyrometer, can also be used to check the fluid temperature. Our TTDT1 comes with a flat probe that can be used to measure the surface temperature of the socket fusion faces of a fusion tool. Pointed probes (PN 5207) can be inserted in the PT ports to measure the EWT (entering water/fluid temperature) and LWT (leaving water/fluid temperature) simultaneously with the heat pump operation. The pyrometer calculates the delta-T for you.
Features of this tool include:
- Dual-channel allows two readings simultaneously for delta-T (differential temperature) measurements
- Accepts Type K or J thermocouples. Our TTDT1 kit includes (1) PN 5208 Type K flat probe for measuring socket face temperatures
- Ambient temperature measurement
- Upper and lower temperature limit alarms
- Adjustable temperature compensation to allow calibration to a known temperature
- Auto power off
- Battery powered (3X AAA); included in TTDT1 kit
- Selectable units (°F or °C)
