The temperature must often be monitored and recorded in two places. With two interfaces for thermocouple probes (Type K and Type T), the testo 175 T3 is suited to this task. For example, in order to test the functionality of a heating system, the flow and return temperatures must be measured and documented. Refrigeration systems are tested in a similar way. In the autumn, the heating season begins, and with it the complaints from tenants that apartments cannot be heated to the desired extent. Using the testo 175 T3 and the versatile pipe clamp probes, you can take targeted measurements of the flow and return temperatures of individual radiators, in order to be able to identify and remedy causes (e.g. silting).
