Testo digital vacuum measurement device testo 552 0560 5522

Evacuation is one of the most important steps when it comes to commissioning or recommissioning refrigeration and air conditioning systems: Foreign gases and moisture must be removed in a reliable manner and to do so, the absolute pressure in the system must be measured. This is exactly what the testo 552 digital vacuum measurement device does: It delivers highly precise information about the dehumidification status in the system and also reliably measures even the smallest absolute pressures. Observe the manufacturer's instructions for evacuation with precision: exceeding limit values immediately triggers a visual alarm. The testo 552 is not affected by moisture and contamination.
