Welch VMpro2 Vacuum Gauge chemical resistant pirani/capacitance combi-sensor 1000 - 10-4 mbar 90-260
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.
