Description
The Dwyer Instruments 2004 Magnehelic Differential Pressure Gauge is a highly accurate product intended used in HVAC systems to measure low differential pressures in the range of 0-4 inches of water column. This gauge uses a diaphragm mechanism to convert pressure variations into dial readings without the use of liquid manometers which may evaporate or may need constant adjustment. The Magnehelic gauge proves most useful in the HVAC systems fitting pressure measurements across the filter, ducts as well as the fans for correct air flow and quality of the systems respectively. It has rather a high-quality design, which ensures its functionality in different circumstances, so it can be used in cleanrooms and industry.
