Testo 552 Digital Vacuum Gauge with Bluetooth Instruction manual
The Testo 552 is a digital vacuum gauge designed for the precise measurement of extremely small pressures in the vacuum range. It is primarily used to monitor the evacuation of refrigeration systems and heat pumps, allowing users to measure current pressure and gather information about dehumidification and the removal of foreign matter. The instrument features Bluetooth connectivity for data transfer and includes a temperature measurement function.
