3.1 Use
The Vac Checkerâ is a digital vacuum gauge for the precise measurement of
extremely small pressures in the vacuum range. This allows you to monitor the
evacuation (usually during commissioning) of refrigeration systems and heat
pumps.
With the Vac Checkerâ, you can therefore measure the current pressure in a
refrigeration system, and thus gather information about the degree of
dehumidification and the removal of foreign matter (oils, foreign gases, etc.).
A vacuum gauge is always used in conjunction with a vacuum pump (generates
the vacuum). A manifold (analogue or digital) is also often used in order to
obtain controlled access to the refrigeration system.
