Pirani gauge sensor

The HPS Series 345 shielded sensor measures from atmosphere to medium vacuum. 345 sensor tubes will operate with the Series 945, 917, 937, and 953 gauge controllers. It has a measurement range of 10-4 torr to atmosphere. Since the sensor is shielded, it can be used in conjunction with CE marked gauge systems, allowing the Series 945 and 937 to be CE marked with Pirani sensors. The sensor can be installed in any orientation, and tubes are interchangeable without user calibration. MKS Instruments Inc., Boulder, CO; ph 800/345-1967 or 303/449-9861, fax 303/442-6880.
