Pressure gauges


Ametek, Horsham, Pennsylvania, introduces its U.S. Gauge line of HVAC pressure gauges. These scales allow the technician to match any given pressure to the temperature saturation point for the type of refrigerant they are using. The scales are labeled with the refrigerant type, alternatively, if the technician doesn’t know what type of refrigerant is in the system, they can find the scale that matches the current ambient temperature and whatever the label is on that scale is the type of refrigerant. U.S. Gauge offers ranges for R-12, R-22, R-502, R-134A, and R410A refrigerants.
