Description
Dwyer 2000 Magnehelic Gage for a versatile low differential pressure gage with a wide choice of 81 models and 27 options to choose from. Using Dwyer’s simple, frictionless Magnehelic® gage movement, it quickly indicates air or noncorrosive gas pressures–either positive, negative (vacuum) or differential. The design resists shock, vibration, over-pressures and is weatherproof to IP67. Also included with the –HA option at no extra cost are a mirrored scale overlay and a 6 point calibration certificate.
Dwyer Series 2000 Magnehelic Features
- Easy to read gage through undistorted plastic face permits viewing from far away
- Patented design provides quick response to pressure changes means no delay in assessing critical situations
- Durable and rugged housing and high-quality components combine to provide longservice life and minimized down-time
- High accuracy option is twice as accurate as the standard Magnehelic® gage.
- Bezel provides flange for flush mounting in panel.
Application
- Filter Monitoring
- Air Velocity with Dwyer Pitot Tube
- Blower Vacuum Monitoring
- Fan Pressure Indication
- Duct, Room or Building Pressures
- Clean Room Positive Pressure Indication
