U.S. Gauge offers ranges for R-12, R-22, R-502, R-134A, and R410A refrigerants, allowing the user to dedicate a HVAC pressure gauge set to each refrigerant, thus avoiding cross contamination. Each HVAC pressure gauge is rugged enough to mount directly on the cooling system or onto a portable manifold. They feature a one-piece threaded plastic ring, allowing quick, easy access to the pointer's internal adjustment screw. Adjusting the pointer to zero before use increases the overall accuracy of the system.
