Essential in refrigeration works for the analysis of the operation of the installation; composed of: 3 hoses, 2 pressure gauges and an angular or straight body. It is used to measure the refrigerant gas pressure in a compressor. Its pressure gauges have a pressure scale of 600 psi. It also has several scales that allow reading saturation temperatures (in ℃) of different refrigerants at a given pressure. Regardless of the scale of the refrigerant. It has standard 2.5" pressure gauges. Made of durable brass and with an easy-to-read sight glass, it features "vibration free" technology for accurate needle measurement.
