The 937B Digital Combination Vacuum Gauge Controller operates up to six vacuum/pressure sensors simultaneously. This highly flexible vacuum gauge controller supports a wide range of sensor technologies, including cold cathode, hot cathode, standard Pirani, convection Pirani, Baratron® capacitance manometers and absolute Piezo sensors for a measurement range from ultra-high vacuum to above atmospheric pressure.

Features & Benefits:

  • Simultaneous readout & control of up to 6 sensors and gauges
  • Operate hot and cold cathodes, Baratron manometers, & Piezo and Pirani sensors concurrently
  • Computer Interface: RS232, RS485 (built in) and Profibus (optional)
  • Modular design can be upgraded or reconfigured in the field
  • Leak test function with bar graph display and audio alarm


With its wide measurement range, the 937B Combination Vacuum Gauge Controller is used in a vast array of vacuum and pressure measurement applications in research, industry, and high technology.

Configure the 937B system:

Add gauge controller boards to the 3 open gauge slots in the base controller under "Configurations" tab below. Find compatible gauges and sensors under the "Related Products" tab.
