Description

Description

  • Robust Vacuum gauge for rough and fine vacuum range
  • Rugged combination sensor combines most advanced Pirani and capacitance membrane technology
  • High accuracy and excellent resolution in the range atmosphere to 5x10-5 mbar
  • Standard or chemical resistant sensor version with built-in LCD Display
  • Available as a package with all accessories for fine vacuum measurement

Multi-range vacuum gauge VMpro 1

DN16KF, 100-240V 50/60Hz


VMpro 1 multi-range vacuum gauge combines Pirani technology with the advantages of a ceramic capacitance diaphragm sensor in a single gauge. 

In the measurement range between 10 mbar and atmospheric pressure the capacitance diaphragm technology provides gas-type independent, highly accurate values for reliable pressure measurement.

The built-in digital LCD display gives clear readability for easy vacuum level monitoring and also shows the current measuring principle. There is a status indication light on top of the sensor 

Scope of delivery: VMpro 1 vacuum gauge, AC/DC power adapter with EU and UK plug adapters, connection cable

Multi-range vacuum gauge VMpro 2

Chemical resistant, DN16KF, 100-240V 50/60Hz 

VMpro 2 chemical resistant multi-range vacuum gauge combines Pirani technology with the advantages of a ceramic capacitance diaphragm sensor in a single gauge. 

In the measurement range between 10 mbar and atmospheric pressure the capacitance diaphragm technology provides gas-type independent, highly accurate values for reliable pressure measurement. 

A Nickel Pirani filament is used to give good compatibility with a wide range of chemicals.

The built-in digital display gives clear readability for easy vacuum level monitoring and also shows the current measuring principle. There is a status indication light on top of the sensor. 

Scope of delivery: VMpro 2 Chem vacuum gauge, AC/DC power adapter with EU and UK plug adapters, connection cable
