Need more Info? (514) 354-2511 - 1-800-463-4363

Differential pressure instrument with membrane measurement technology for monitoring and control of differential pressures and air flows in HVAC applications. Suitable for rooms and ducts.

By the integrated switch the pressure conditions can be monitored and an alarm set in case of need. The also integrated analogue outputs (V and mA) can be used for a system control. The automatic Zero-Point calibration assures an accurate and reproducible measurement at any time and avoids any influence of the mounting position on the measurement results.

The configuration and calibration of the PascalMaxx can be easily done by the front keypad.


  • Easy startup
  • High precision silicon membrane sensor
