The Testo 570 Refrigeration System Analyzer is equipped with a 4-way valve block, that's ideal for installing and troubleshooting all types of refrigeration, heat pumps and AC systems. Use it daily for calculating superheat and sub cooling simultaneously, in real time, with two external temperature probes. During heat pump mode the 570 saves you time by automatically switching over the high and low side pressure and temperature without having to change the hoses.

For long term or multiple measuring cycles the 570 can be programmed and left to automatically collect and store data for up to 72 hours. This internal memory gives the technician the ability to accurately diagnosis system errors that could easily have been missed in a manual process.

Use testo's easyKool software, exclusive to testo RSA's, for complete data management, providing onsite reports to customers, and printing and displaying measuring results.

Kit includes:

  • 2 Clamp probes (NTC)
