Dwyer AT22000 Flameproof Magnehelic® Differential Pressure Gauge is the industry standard to measure fan and blower pressures, air velocity, furnace draft, the pressure drop across orifice plates, liquid levels with bubbler systems, and pressures in fluid amplifier or fluidic systems. A flame-proof ATEX has a glass window for viewing the pressure range on the gauge face.
Features of Dwyer AT22000 Flameproof Magnehelic® Differential Pressure Gauge:
- ATEX/IECEx housing provides all the capabilities and value of the Magnehelic® in a flameproof enclosure
- Quick response to pressure changes means no delay in critical situations
- Durable and rugged housing and high-quality components provide long service life and minimized downtime
- High impact strength and high-temperature rating for applications where hazardous environments exist
