HCS2038-11 – Magnehelic® Differential Pressure Gauge

HCS2038-11 – Magnehelic® Differential Pressure Gauge

The HCS2038-11 Magnehelic® Pressure Gauge is the industry standard to monitor and measure positive pressure in clean rooms, fan and blower vacuum pressures, and filter resistance.

This gauge quickly indicates air or noncorrosive gas pressures–either positive, negative (vacuum) or differential. We offer this gauge in a kit or sold as a single unit.


The Magnehelic® Differential Pressure Gauge quickly indicates air or noncorrosive gas pressures–either positive, negative (vacuum) or differential making it a great addition for a clean room facility.

  • Clear plastic face is highly resistant to breakage
  • Easy to read gauge through undistorted plastic face permits viewing from far away
  • Provides quick response to pressure changes
  • Durable and rugged housing and high-quality components combine to provide long-service life and minimized down-time
  • High accuracy option is twice as accurate as the standard Magnehelic® gauge
  • Service: Air and non-combustible, compatible gases.
