Testo's 557 digital manifold has a 4-way valve block, a large backlit display, and a sight glass. Two NTC thermistor clamp probes provide superior accuracy for simultaneous, real-time superheat and subcooling readings. An external vacuum probe provides fast and reliable evacuation of the system. 


The wireless Bluetooth / app allows you to view measurement data on your smartphone or tablet, enabling you to quickly and conveniently complete and document your job. You also can finalize documentation and send reports and invoice via email, right from the job site. In addition to the 60 refrigerant profiles stored in the instrument, the app can be used to download new refrigerants from the Internet, directly to the digital manifold. 

The 557 Kit comes with two NTC temperature clamp probes, external vacuum probe, batteries, case and certificate of conformity.
