Yellow Jacket 78052 Digital Dual Port Manometer

The new dual port manometer has all of the capabilities of the old 78050 (Single Input Manometer – discontinued) in addition to the following:

  • capability to measure pressure drop directly across two points such as filter pressure drop or flow volumes, and;
  • positive and negative pressures can be read directly if measured on the appropriate input.

The 78052 is a portable, rugged dual port manometer designed especially for HVACR field service technicians. Its range and resolution allow measurement of every day HVAC applications.



  • Measures gas pressure, static pressure and pressure differential
    • Measure gas pressure on the inlet and outlets with the standard 1/8 NPT fittings or directly with the adapter for WR gas valves
    • Take static pressure measurements using the resolution mode of 0.01inWC
    • Read pressure differential measurements across a blower directly
  • Includes a easy to use zero function
  • Auto Power-Off (APO) conserves battery life
  • Measures pressure between -19.95 and 19.95inWC (inches of water column)
  • Individual P1 or P2 measurements can be made by disconnecting the other port thus referencing the measured pressure to atmospheric pressure


Kit includes 30′′ tubing, clear hose, tube splice and 1/8” NPT brass fitting.
