The Ewards WRG-SL Active Wide Range Gauge NW25, KF25, produce a lower magnetic field for particularyly sensitive insturment application, such as, mass spectrometry and microscopy. They offers the capability of single port pressure measurement in the range ATM (atmosphere) to 10^-9 Torr 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 and has a user replaceable sensor tube.

The WRG is suitable for a wide range of HV and UHV applications, however if your process will spend a significant amount of time between 5x10^-4 Torr and 5x10^-3 Torr then Edwards recommend using independent APG100 Pirani and AIM Penning gauges, as this will improve gauge reliability for your application. Signal cable and controller not supplied. For instruction manual .pdf on Edwards WRG Active Wide Range Gauges see below AVAILABLE DOWNLOADS:
