The testo 570 4-valve digital manifold has an internal vacuum sensor, data logging and printing capabilities, as well as an additional third probe port for either ambient temperature, current, or oil pressure probes. the testo 570 can replace a whole range of measuring tools that you would normally need to carry out your work on refrigeration systems and heating pumps. This manifold can measure, analyze, and log pressure, temperature, electricity, and vacuum measurements, and save all data, from the second the meter is switched on, to the final analysis of a system. -999 hours of internal memory – clearly structured, easy to follow -Real-time data measurement and graphical editing with optional EasyKool software. -Call up and print out protocols and reproduce measurements easily -40 refrigerants are already stored in the meter, and free updates of other refrigerants are available. -Two temperature compensated pressure sensors for quick and reliable high / low pressure plus automatic temperature measurements -Three temperature connecting ports for connectable temperature sensors, allowing simultaneous superheat / subcooling calculations and parallel surrounding temperature measurements, such as for cold storage room applications -Integrated vacuum measurements for the evacuation of refrigerant systems / heat pumps -Automatic heat pump mode – no need to replace refrigerant hoses -Further features include temperature compensated leak-tightness check function, and automatic surrounding pressure compensation
