Made in Germany Testo557 Digital Manifold with Bluetooth and External Vacuum Probe No. 0638 1557

Product Description

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)

Features

• 4-way valve block
• New Bluetooth connectivity and App makes it easier than ever to manage your jobs
• Even more precise external probe for even more reliable performance
• Improved robust design and extremely convenient operation
• Measurement of low and high pressure as well as calculation of temperatures
• Simultaneous calculation Of superheating and subcooling in real time
• 60 refrigerants already stored in instrument

Quick, precise measurement of high and low pressure: two temperature-compensated pressure sensors make this possible and automatically calculate the theoretical evaporating and condensing temperature
Simultaneous calculation of superheating and subcooling: do away with manual calculations, which are time-consuming and during which errors often creep in
Precise external Pirani gauge for vacuum measurement: you get a high-precision Pirani gauge with the digital manifold, enabling you to carry out accurate vacuum measurement and making it easier to evacuate refrigeration systems and heat pumps
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 and adapt to suit your requirements
