Welch VMpro1 Vacuum Gauge pirani/capacitance combi-sensor 1000 - 10-4 mbar 90-260V 50/60Hz with AC/D
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 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.
