Dwyer Instruments 2000-00N Magnehelic Differential Pressure Gauge 0.05"- 0.20" WC

The Dwyer Instruments 2000-00N Magnehelic Differential Pressure Gauge is a highly accurate product used for measuring low differential pressure with a range of 0.05”- 0.20” water column. This gauge uses a diaphragm mechanism which eliminates mechanical connections and makes the part accurate and reliable as pressure variations are directly translated into readable scale. It can be found commonly in HVAC systems that to measure filter conditions or fan pressure for clean room/airflow applications etc. The advantages of the Magnehelic gauge are that it is shock and vibration-proof and does not require liquid manometers which can evaporate or need frequent recalibration.
