Testo 557 Wired Digital Thermometer for Transport Use, NTC Probe, 2 Input(s), +150°C Max, ±0.5 °C Accuracy

The Testo 557 digital manifold is an easy-to-use, 4-way valve, block measuring device with a temperature ranging between -50°C to 150°C. This instrument fulfils numerous functions working on refrigeration systems and heat pumps such as superheating/ sub cooling calculation, vacuum measurement and temperature-compensated leakage test. You can also use a practical app to monitor the manifold via your smartphone/tablet and store the measurement results or send them by e-mail. This instrument includes 2 clamp temperature probes, precise external Pirani gauge for vacuum measurement, transport case, calibration protocol, batteries and a downloadable app.
