Digital Manifold Kit with Bluetooth L35913
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.
