Testo Introduces Maintenance-Free Vacuum Gauge
Testo Inc. has introduced its 552 Digital Vacuum Gauge, which confirms the evacuation of air conditioning, heat pump and refrigeration systems. The testo 552 requires no cleaning, nor is it susceptible to contamination from oils, the company says. And, the absolute pressure sensor delivers fantastic accuracy to +/-10 microns.
Outfitted with a large back-lit display, and rugged IP 42 Protection Class (dust & 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,
- 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.
