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.

• Simultaneous readout & control of up to 6 sensors and gauges
• Wide measurement range from 10^-11 to 20,000 Torr
• Operate hot/cold cathodes, manometers, and Piezo/Pirani sensors concurrently
• Modular design can be upgraded or reconfigured in the field
• Leak test function with bar graph display and audio alarm
• Computer Interface: RS232, RS485 (built in) and Profibus (optional)
