The best way to prevent an outbreak of Legionnaires’ disease is to ensure that any water system under your control is properly maintained and conforms to the relevant health and safety regulations. 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.

With the Testo 175 T3 and the versatile external thermocouple probes, you can, for example, perform targeted checks on the flow and return temperatures of individual radiators, in order to identify and remedy causes.

You can display the current measuring values, min./max. values, set limit values, violations of limit values and remaining battery life on the clear display. This means you have the opportunity to read important values at any time and do not need to resort to a read-out of the temperature logger on the PC straight away every time you want to do a quick data check.

The ComSoft Basic software (free download) allows fast programming of the data logger and easy data analysis.

High data security.

Up to 3 years’ battery life.
