The Series 937B combination vacuum gauge system is part of the HPS® family of vacuum gauges. It is the third generation of the very successful 937 Series. The 937B will operate and display as many as six sensors simultaneously, and each controller can be configured to the user’s gauging requirements. This highly fl exible product enables a wide range of gauging technologies, tailoring the system to each individual application. The Series 937B combines the sensor technologies of the cold cathode, hot cathode, standard Pirani, convection Pirani, MKS Baratron® capacitance manometer and absolute Piezo sensors to measure from ultra-high vacuum to above atmospheric pressure.
