Areas of application

Drying is one of the most important work steps when it comes to the commissioning or re-commissioning of refrigeration and air-conditioning systems: foreign gases, moisture and oils must be reliably removed and for this purpose the absolute pressure must be measured of the plant.
The testo 552 vacuum gauge was designed for this very purpose: it helps to understand the dehumidification status of the system and reliably measures even the smallest absolute pressure values. Equipped with a rising alarm to make sure that drying has taken place correctly.
