300564 5571 02Large graphic display allows all measurement values at a glance. IP54 protection for use outdoors.
Test menu sequences for pressure leak test, vacuum, discharge line temperature, and target superheat
Suitable for use on monobloc or split heat pump systems
Supplied with testo 770-3 clamp meter for compressor current testing and testo 560i digital scales with automatic controlled charging valve for refrigerant charging
Simple digital documentation and 'on-site' reporting via bluetooth coonnection to free Testo Smart App.
With this kit, you’ll be ready to start your measurements in the commissioning, servicing and maintenance of heat pumps, refrigeration, or air-conditioning systems straight away: You will get the testo 557s smart digital manifold with Bluetooth and 4-way valve block, two testo 115i bluetooth temperature pipe clamp probes allow simple measurement of superheat and subcool values whilst the testo 552i Vaccum smart probe provides bluetooth measurement during system evacuation procedure. The testo 770-3 clampmeter can be used for compressor current measurement, and completing the package is the testo 560i digital refrigerant scales for accurate and effective charging of refrigerants in conjunction with the Testo smart valve.
