Therma Differential Two-channel differential thermometer

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 the temperature of probe T1 or T2, or the difference between probe T1 and T2 (T1-T2). This allows, for example, the measurement of temperature drop across radiators or the temperature rise or fall of two objects.

The Therma Differential measures temperatures in the range of -99.9 to 299.9 °C with a resolution of 0.1 °C or from 300 to 1372 °C with a resolution of 1 °C. The thermometer features a custom LCD display with °C, T1, T2, difference, hold, open circuit, battery indicator and optional backlight. The device has an auto-power off function that automatically switches off the instrument after about ten minutes, maximizing battery life.

Each thermometer is housed in a durable ABS case with an integrated rubber seal for full waterproofing and to reduce the chance of damage in harsh environments.

The price of the Therma Differential does not include the measuring probe.
