General information

Pressure scale:
M = metric, bar
DS = double scale bar/psi
KPA = kPa/psi

Standard Refrigerant Temperature Scales:
R12 = R12/R22/R502
R12-N = R12/R22/R134a
R134a = R134a/R404A/R507
R22 = R22/R134a/R404A
R407C = R407C/R134a/R404A
R410A = R410A
CLIM = R22/R407C/R410A
MULTI = R22/R134a/R404A/R407C

REF-CLASS-GAUGE

The digital pressure test gauge takes
the concept of an analog gauge, and
brings it to a new level, as only digital
calibrators can do. The REF-CLASS-GAUGE combines the accuracy of digital technology with the simplicity of an analog gauge. It achieves performance, ease-of-use and features unmatched in the pressure measurement world.

The versatility of this high-end product is your benefit. The REF-CLASS-GAUGE allows you to test the pressure of gauges on your own and in addition helps to save costs. For instance the digital manifold “DIGIMON” can easily be calibrated in-house.

The REF-CLASS-GAUGE offers a comfortable and compact solution in order to perform pressure calibration on-site. The setup is fast and straightforward, through a menu-driven display with minimal test and intuitive functions. A carrying case protects this precision device in a perfect way.


  • Simple generation of test pressure on-site, in lab or in the shop floor
  • For testing, setting and calibrating of any pressure gauges
  • Pneumatic pressure generation of 950 mbar to +35 bar
  • Ergonomic handling
  • Precise alignment through fine-control valve
  • Accuracy: 0,05% FS (incl. calibration certificate) for pressure- and temperature measurement
  • Rugged stainless steel case meets NEMA 4/IP65
  • Data logger function
  • Data interpretation software o demand
