Testo 550-01

Testo 550-01 RSA Basic Refrigeration System Analyzer Kit with Clamp Probe, -58 to 302 Degree F Range. Testo refrigeration system analyzers (RSA) are high performance instruments that accurately perform temperature and pressure measurements in seconds. Includes clamp probe, batteries and certificate. These instruments provide fast, real-time superheat and subcooling readings for 39+ profiles in real-time. Built rugged for the field, Testo RSAs give you the accuracy and repeatability you've come to expect from Testo. The testo 550 RSA is ideal for servicing, maintaining and commissioning, refrigeration and heat pump systems including the newest 16 SEER systems. Compact design, hardened housing and extremely convenient operation for ease-of-use, transport and setup. Measurement of low and high pressure as well as calculation of temperatures, fast and accurate. Performance, value and speed cool. Real-time superheat and subcooling readings. Simultaneous digital readout of temperatures and pressures. Pipe clamp temperature probe (0.2 - 2.5" diameter). Built-in magnifying sight glass. Two NTC temperature probe inputs. Fast response time.
