Pressure measurement - Vacuum

An essential step in the procedure before commissioning or recommissioning of a refrigeration or air conditioning system is evacuating the system itself. Moisture, gases, oil and refrigerant residues are removed during evacuation. Testo vacuum gauges assist you to assure a proper evacuation - which is critical to assure proper working condition. 

Did you know: The testo 552 can be paired with the Testo 570 refrigeration manifold, which means you could log/record vacuum measurements.
