testo 557 Digital Manifold Set

Part Number : 0563 1557

Product Description:
 
The Testo 557 digital manifold fulfils numerous functions, which are required for working on refrigeration systems and heat pumps, in just one instrument: for example superheating/subcooling calculation, vacuum measurement, 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.

Key Benefits:

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

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).

testo 557 Digital Manifold Set

Area of Application:
 
Are you primarily entrusted with the commissioning or maintenance of refrigeration systems or heat pumps? If so, the testo 557 is the ideal digital manifold for you: like the testo 550, this digital manifold replaces multiple tools in the refrigeration industry and can be connected to a practical app. As well as the features of the testo 550 manifold, the testo 557 offers a high-precision external Pirani gauge for vacuum measurement: this enables the quick, safe evacuation of refrigeration systems and heat pumps. 

Clamp probe (NTC) for temperature measurements on pipes (Ø 6-35 mm) with 5 m cable length – measuring range: -40 to +125 °C
