Therma Differential Two-Channel Differential Thermometer

The Therma Differential digital thermometer is an ideal HVAC thermometer because 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 makes it possible, for example, to measure the temperature drop across radiators or the temperature rise or drop 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 showing °C, T1, T2, difference, hold, open circuit, battery indicator, and optional backlight. The device has an auto-off function that automatically turns the instrument off after approximately ten minutes, maximizing battery life.

Each thermometer is housed in a durable ABS casing with an integrated rubber seal to ensure complete water resistance and minimize the risk of damage in harsh environments.

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