testo 557s - Heat pump kit

300564 5571 02

Large 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

A3 and A2L compatible and over 90 stored refrigerants

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.
