One of, if not the best value in Digital Refrigeration Gauges, the Testo 550 is a rock solid every day performer for residential and commercial service. Easy to use, the 550 will dramatically increase your productivity and efficiency by allowing you to quickly charge and service A/C and refrigeration systems with unrivaled confidence in your readings. TruTech Tools has sold 100's of 500 series manifolds, and for us, the 550 has an excellent track record as being one of the most reliable RSA's (Refrigeration System Analyzers) on the market. Loaded with features including altitude compensation, a temperature compensated tightness test, 31 refrigerant profiles, automatic calculation of superheat and subcooling, the Testo 550 is simply on of the best values you can get.
