Differential Pressure Gauges - Mag DP (Pharma Application)



“General” make Mag-DP Gauges are designed for measuring very low differential pressures. Minimum measuring range offered is as low as 0 to 6 mmWC(DP). The Mag-DP Gauges are suitable for measuring fan & blower pressures, filter resistance, furnace draft and pressure drop across orifice plates, etc. Mag-DP Gauges are designed to suit Flush Panel Mounting or Sur face (Projection) Mounting or Yoke (2” Pipe) Mounting as per requirement. For maximum accuracy, it is recommended to mount the Gauge in vertical position. Suitable mounting accessories are provided with each Gauge.
