Standard Differential Pressure Gauge (DPG) with Membrane Sensing Element and needle pointer for pressure, differential pressure and depression measurement.
Best alternative compared to Liquid Column Manometers, because it requires no maintenance.
Differential Pressure Gauges are suitable for the monitoring of fans, air filters and non-aggressive gases.
For the correct use remember that:
- the indicator is calibrated and zeroed in the vertical position, when it is used in any other position must be reset;
- the direction of the pressure input can be changed to be positioned up or down with the angled pressure connectors.
