Incline Manometers
Cost‑effective, instruments used to measure pressure differentials across air filters. They use a coloured liquid to display the pressure in Pascals (Pa). They are generally less accurate than other gauge types, and the indicator liquid may fade over time, making readings harder to see.
Typical Measuring Range: 0-500Pa (1908701)
Magnahelic Gauges
A circular dial with a needle to display differential pressure in Pascals. Although more expensive than incline manometers, they offer significantly higher accuracy, and are also suitable for sensitive environments such as hospitals, laboratories, and cleanrooms.
Range Options: 0-60Pa (1908702), 0-250Pa (1908702) 0-500Pa Part Number: (1908702)
(Other Scales Available Upon Request)
Pressure Switches
Pressure switches do not provide a pressure reading on the device itself but trigger an electrical signal at a set pressure point and can be integrated with a Building Management System (BMS) to activate indicator lights or alarms.
Range Options: 20-300Pa (1908703) – (Other Scales Available Upon Request)
