Overview
The Testo 570 is a robust digital manifold 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 subcooling 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.
