PascalMaxx MEMBRANE product line

PascalMaxx membrane differential
pressure measurements instruments
for clean rooms and HVAC applications

Differential pressure measurement, made easy!
The PascalMaxx, a measurement instrument for pressure ranges up to
2000 Pa, which is typically used in HVAC (Heating, Ventilation, Air Conditioning) or clean room applications (50 Pa version), is provided with the
most modern technology. Thanks to the high quality membrane sensor, optimised measurement electronics and integrated automatic zero-point
calibration this device is able to measure pressure differences at high levels with best accuracy, repeatability and stability.
Various functions, which can be chosen and set by the front keypad buttons make this system extremely versatile and adaptive. For each application, even the most specific, this instrument can be configured and integrated perfectly.

Accurate, fast, versatile, adaptive, robust, stable, cost efficient
With the new PascalMaxx, Novasina widens its product line. After the
HygroMaxx for rel. humidity and temperature measurement Novasina
launches now the new differential pressure measurement instrument for
ranges up to 2'000 Pa.
The PascalMaxx outstands by its versatility and easy operability. A real
added value is offered by the integrated fully automatic zero-point
calibration system, which is adjusting drifts continuously and makes the
measurement device stable and insensitive to mounting position.
