Product Description

4 valves smart digital manifold Gauge testo 557 digital manifold

1. Calculation of superheating and subcooling in real time: no manual calculation, which is prone to error
2. Connect to smartphone/tablet app: remote monitoring and smart measurement documentation
3. Precise external Pirani gauge for vacuum measurement, temperature-compensated leakage test, automatic ambient pressure
measurement
4. The 60 most common refrigerants are stored in the instrument, subsequent updates possible (via app)

Product Description
Start your wireless measurements on refrigeration and air conditioning systems and heat pumps straight away. Thanks to the Blue
tooth vacuum probe supplied, you can even measure vacuum without any cables or hoses. You will get the testo 557s smart digital
manifold with Blue tooth and 4-way valve block, one testo 552i wireless vacuum probe (Blue tooth), two testo 115i wireless clamp
thermometers (Blue tooth, NTC) and a robust transport case. For Other wireless measurements, other optionally available testo
Smart Probes are also ideal.

Delivery Scope
testo 557 digital 4-way manifold including two clamp temperature probes, precise external Pirani gauge for vacuum measurement,
transport case, calibration protocol, batteries and app (can be downloaded).
