SDMN5 - Manometer Dual Port

A rugged, versatile dual-port manometer specifically designed for HVACR technicians.

This tool measures:

- Gas pressure

- Static pressure

- Pressure differential

The SDMN5 allows you to easily and accurately measure pressure on HVACR systems you see every day on the job.


The SDMN5 is a rugged, versatile tool made for the HVACR industry. The tool includes a zero adjust button, a rubber boot for protection, a magnet on the back to easily hang the meter during service, and the Auto Power-Off function to save battery life.

The tool measures pressure between -60inWC and 60inWC, as well as -150.0 to 150.0 mBar. On top of that, the tool also measures P1 and P2 pressure readings and automatically calculates the difference, allowing you to focus on the system itself.

With the SDMN5, you can measure pressure on standard 3/16" fittings as well as 5/16" ports. It's versatile and rugged, perfect for any measuring job!
