Edwards WRG200 Active Wide Range Gauge | WRG200-x-NW25

The Edwards Active Wide Range Gauge (WRG200) offers the capability of single port pressure measurement in the range atmosphere to 10-9 mbar with a linear output.

Measurement Range: 750.06 to 7.501 × 10⁻¹⁰ Torr
Accuracy: 50 to 1×10-2 mbar ±15% | 1×10-2 to 1×10-8 mbar ±30%

The WRG200 is a compact and efficient solution that significantly reduces the required space and hardware for connectivity. Its compact design makes it ideal for various applications. This gauge has undergone numerous technical improvements such as its innovative striker design, a 3600 LED light ring, easy push-button calibration, integrated set-point controls, and comprehensive diagnostics.

Features and Benefits

  • 360° LED light ring visual pressure indicator
  • Reduced footprint
  • Multipoint star striker
  • Analogue/digital
  • Wide range power supply
  • Drop in compatible
  • New magnets
  • Set-point relay


The WRG200 offers cost-effectiveness as a vacuum management solution, either when used with an Edwards controller or directly integrated into the system controls. This gauge is perfect for monitoring pressure in systems that are rapidly pumped down from atmospheric pressure to high vacuum levels.

Broad Range Vacuum Gauging

Broad 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.
