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
