The Pressure Indicator offers a standardized means of displaying pressure levels in collective protection (ColPro) systems.

This indicator combines a Magnehelic® gauge, custom gauge markings, and a painted bracket for wall (bulkhead) mounting. The gauge displays differential pressure based on low and high pneumatic inputs, and requires no electrical power.

The indicator is available in three pressure ranges: 0-1 in wg, 0-4 in wg, and 0-10 in wg. The lower ranges are ideal for monitoring zone pressure. Higher ranges can be used for measuring filter flow restrictions.
