- Extremely precise, rugged and practical: the testo 552 digital vacuum gauge. Ideal for evacuating refrigerant systems or heat pumps.

Description:

The testo 552 is a digital vacuum measuring instrument for the evacuation of refrigeration systems and heat pumps.

It measures even the smallest absolute pressures and provides highly precise information on the status of the dehumidification of a system (removal of foreign substances, incl. oils or foreign gases).

The testo 552 is the only digital vacuum measuring instrument whose absolute pressure sensor, in contrast to other sensor technologies, no longer needs to be serviced, and still provides highly accurate measurement results.

The battery life of up to 2400 hours with 2xAA batteries, you can use the testo 552 in continuous operation for 100 days without changing the battery.

Its robust construction makes it suitable for daily use, and protects from dirt and water.

The Testo 552 uses Bluetooth to link to your smart phone or device utilizing the free Testo SMART Probes App, which is a powerful and easy-to-use tool to remotely read measurements.
