Dwyer 2000 Series Magnehelic Differential Pressure Gauge
Product Description
Dwyer 2000 Series Magnehelic Pressure Gauges
Low pressure Magnehelic gauges with frictionless movement to quickly indicate positive, vacuum or differential pressures.
Select the Series 2000 Magnehelic® Differential Pressure Gages for a versatile low differential pressure gauge 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.
Select the –HA High Accuracy Magnehelic® gage option for an accuracy within 1% of full-scale. Also included with the –HA option at no extra cost are a mirrored scale overlay and a 6 point calibration certificate.
