Ritchie Yellow Jacket 78052 Digital Dual Port Manometer

SKU Ritchie Yellow Jacket 78052 Digital Dual Port Manometer

The new dual port manometer has all 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 0.01" WC
• Read pressure differential measurements across a blower directly

Includes an easy to use zero function

Auto Power-Off (APO) conserves battery life

Measures pressure between -19.95 and 19.95" WC (inches of water column)

Individual P1 and 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.
