HPS 937 MKS Instruments Gauge Controller

The MKS Instruments HPS 937 Series High Vacuum Multi-Sensor System uses the technologies of the cold cathode, standard Pirani, convection Pirani, and thermocouple sensors and the capacitance manometer together to measure pressures from as high as 10,000 Torr down to ultra high vacuum. The System operates as many as five sensors simultaneously. The Series 937A Controller is configured to your specifications - you choose the type and number of sensors, the line voltage, frequency, units of measure, and communications interface.

A large, easy-to-read liquid crystal display (LCD) provides simultaneous pressure readings for all sensors. If a sensor is turned off, not connected properly, or used out of range, a relevant message replaces its pressure reading. The Controller's Function Select rotary switch and push-button labels are color-coded to simplify use. Near each sensor's readout, white space is provided so that you may write in sensor information specific to your system.

The Controller can be set up with a cold cathode sensor module and two more sensor modules to operate either capacitance manometers or cold cathode, Pirani, Convection Pirani, or thermocouple sensors. After setup, you can confirm your settings with the Controller's setup review feature. A display message will let you know if the Controller has detected a broken sensor wire or improper connection for the Pirani, thermocouple, and Convection Pirani sensors.
