testo 550-1 Set digital installation aid with Bluetooth for refrigeration systems and heat pumps

testo 550-1 set, digital installation aid with Bluetooth üfor service and maintenance of cooling systems and heat pumps, incl. clamp meter, calibration protocol and batteries.

testo 550: just switch on, measure and read. Large numbers make it quick and easy to read the values on the display. Two temperature-compensated pressure sensors measure high and low pressure quickly and precisely and automatically calculate the temperatures.
A single glance at the device display is enough to see the measurement result.
Two temperature inputs ensure the simultaneous calculation and display of overheating and undercooling. In addition, the temperature difference can be displayed.
You can switch between the measurement tasks simply by pressing a button.

• The testo 550 digital installation aid, ideal for all measurement tasks on refrigeration systems and heat pumps.
• Measurement of high and low pressure and calculation of temperatures
• Simultaneous calculation of superheating and subcooling in real time
• 39 refrigerants already stored in the device
