WRG-SL-NW25, Certificated
HVC-D1471100C
The Wide Range Gauge (WRG) family offers the capability of single port pressure measurement in the range atmosphere to 10-9 mbar with a linear output. Its a compact solution, halving the space and connectivity hardware requirement, which can be all important in many applications. The WRG has many novel features, including a new patented striker, pushbutton calibration and set point controls and comprehensive diagnostics. The WRG is a cost-effective vacuum management solution when used either with a Edwards controller or directly integrated into the system controls.
