Testo Inc. has introduced the 552 Digital Vacuum Gauge to confirm the evacuation of air conditioning, heat pump and refrigeration systems. Unlike other vacuum gauges, the testo 552 requires no cleaning, nor is it susceptible to contamination from oils.  Aside from this big time savings benefit, the absolute pressure sensor delivers fantastic accuracy to +/-10 microns.

Outfitted with a large back-lit display, and rugged IP 42 Protection Class (dust and splash resistant) housing, the testo 552 is tough enough to withstand a 6 foot drop.   Additional features include long battery life to 2400 hours, a high limit alarm, and display of water evaporation temperature.  For owners of the testo 570 Digital Manifold, the testo 552 can be connected to the t570 to data log and/ or print your evacuation data.

John Bickers, director of product management, adds, “The industry has been looking for a no clean, no maintenance vacuum gauge that they can count on, we are very happy to answer with the testo 552.”
