HDT’s Pressure Indicator provides a standardized means of displaying pressure levels in collective protection (ColPro) systems.

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