The Therma Differential digital thermometer is an ideal HVAC thermometer as it allows the user to use two type K thermocouple probes simultaneously.
The display can be switched to show probe T1 or T2 temperature or the difference between probes T1 and T2 (T1-T2). This allows, for example, the temperature drop across radiators or the temperature rise or fall of two items to be measured.
