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.
- 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)
- Quick, precise measurement of high and low pressure: two temperature-compensated pressure sensors make this possible and automatically calculate the t
- Simultaneous calculation of superheating and subcooling: do away with manual calculations, which are time-consuming and during which errors often cree
- Precise external Pirani gauge for vacuum measurement: you get a high-precision Pirani gauge with the digital manifold, enabling you to carry out accur
- Two clamp temperature probes included in the delivery: clamp them to the cables to reliably measure the surface temperature
- No need to switch over refrigerant hoses: thanks to automatic heat pump mode
- Can be used for 60 current refrigerants: 60 refrigerants are stored in the manifold, which you can update if necessary via the smartphone/tablet app a
