This manual provides instructions for operating, maintaining, and calibrating the Testo 552 digital vacuum gauge used for measuring low pressures in…
The Testo 552 is a digital vacuum gauge designed for precise measurement of extremely small pressures within the vacuum range. It is primarily intended for monitoring the evacuation of refrigeration systems and heat pumps, allowing users to measure current pressure to assess dehumidification and the removal of foreign matter like oils or gases. The device operates as a probe in conjunction with a vacuum pump and can be used with manifolds. This manual is written in German.
