0563 5505 550-1 Refrigeration System Analyzer (RSA) Basic Kit by Testo

testo 550: just switch on, measure, and read off Large figures allow the values to be read off the display quickly and easily. Two temperature-compensated pressure sensors measure high and low pressure quickly and precisely, and automatically calculate the temperatures. A glance at the instrument display is enough, and you see the measurement result. Two temperature inputs guarantee you the simultaneous calculation and display of superheating and subcooling. The temperature can additionally also be displayed. By simply pressing a button, you can switch between the measurement tasks at your will.

Kits includes:

• 550 Refrigeration System Analyzer
• 0613 5505 - Clamp probe (NTC)

• The digital manifold testo 550, ideal for all measurement work on refirgeration systems and heat pumps
• Robustness 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
• 39 refrigerants already stored in instrument
