Areas of Application:

Sensor change by customer

The simple design of the Testo 316-3 enables the sensor to be changed in just a few seconds and means the sensor is always ready for use.

Tightness testing of refrigeration systems

The Testo 316-3 meets all the requirements of the F gases regulation thanks to the high sensitivity of 4 g/a. This means you can find every leakage – no matter whether it involves an R22, R134a, R410a or another refrigerant.
