Wide Range Gauge
The Active Wide Range Gauge family offers the capability of single port pressure measurement in the range atmosphere to 10⁻⁹ mbar. This gauge is particularly suited to monitoring the pressure on systems that are rapidly pumped down from atmosphere pressure to high vacuum levels.
The WRG is a cost-effective vacuum management solution when used either with an Edwards controller or directly integrated into the system controls.
All gauges feature compact size for easy installation, a serial output and a replaceable sensor tube. They are also CSA and C/US approved as well as fully RoHS compliant due to their lead-free construction.
