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.
