Efficient: The testo 557 is ideal for servicing air conditioners, refrigeration systems and heat pumps and replaces the multitude of tools needed by HVAC/R contractors and technicians
Versatile: Accurately measure high and low pressure, evaporation and condensation temperature and take advantage of the automatic calculation of superheating and subcooling
Convenient: Thanks to the 4-way valve and automatic heat pump mode, there is no need to switch over to different refrigerant hoses, which enables a quick and easy application
Set: Includes two pipe clamp temperature probes, one external pirani probe for vacuum measurement and a set of four hoses, as well as a protective hard-shell case
Testo 557 - Digital manifold for accurate measurement and documentation Installation and maintenance of air conditioning, refrigeration systems and heat pumps has never been more convenient. Store up to 60 refrigerants in just one instrument simply update them in the app and accurately measure high and low pressure along with evaporation and condensation temperature. Attached to the valve block inputs, the included pipe clamp probes reliably measure pipe temperature and provide simultaneous calculation of superheating and subcooling. The handy refrigeration app offers a variety of practical features. With a connection of up to 60 ft., the app offers remote monitoring of measurements in numeral form or graphical progression from a smartphone or tablet. Results can be quickly stored and sent directly from the job site via e-mail.
