Gauge Indirect Pressure Measurement
Indirect braod range vacuum gauges are the best choice when the pressure needs to be measured over a wide range and when good accuracy is needed across the whole range. Reliable vacuum gauges are essential to ensure your system’s accuracy and control. Our vacuum gauging solutions include the WRG Series Cold Cathode Combination Gauge, AIM Series Cold Cathode Gauge, and APG Series Pirani Gauge.
WRH Series Hot Cathode Combination Gauge
The Active Hot Cathode Wide Range Gauge (WRH) offers the ability to measure from atmosphere to 10-10 mbar with a single gauge, with accuracy and repeatability.
The WRH gauge utilises 2 measurement methods (bayard-alpert & pirani) in a single package, giving you everything you need to measure and control your system. With analogue and RS485 output available via the D-SUB connector, 2 onboard relays and easy calibration, control and monitoring is simple. Utilising the included software, you can easily track and log your system’s performance and also make adjustments to the gauges behaviour, such as setting the set points or changing the output scaling. This gauge is the perfect companion for many applications, from R&D institutes to high end mass spectrometry and through to general industry.
