Product Details

Testo Digital Manifold

The Testo 550 digital manifold is an easy-to-use, 2-way valve, block measuring device with a temperature ranging between -50°C to 150°C. This instrument is made of metal with 3 connections and 3 hose holders, created for harsh working environments. The sturdy housing reliably protects against impacts whereas, the suspension hook secures the instrument during the measurement. This instrument can be used for 60 refrigerants, calculates superheating/ sub cooling automatically and can now also be connected to a practical smartphone/tablet app. The app makes the operation and the documentation of measurement results significantly more convenient. The instrument contains 2 clamp temperature probes, transport case, calibration protocol, batteries and a downloadable app.
