Testo 552 - Digital vacuum gauge

Product #5522

Evacuating is one of the most important steps when it comes to installing or restarting refrigerant or air conditioning systems: foreign gases, moisture and oils have to be removed properly. That’s when the absolute pressure of a system needs to be measured.

And that’s exactly what the testo 552 digital vacuum gauge is designed to do: the meter provides you with highly accurate information regarding the dehumidification status of the system and is able to measure even the smallest of absolute pressures absolutely reliably. A visual alarm warns immediately when a threshold has been exceeded.

Product benefits:

  • The only digital vacuum gauge of its kind with maintenance-free yet high-precision absolute pressure sensor
  • 2 400 hours of battery power for 100 days of continuous operation
  • Extremely precise, extremely rugged, extremely practical – with visual alarm and backlit display
  • Measures pressure and calculates the evaporation temperature of H2O automatically
