SDMN5, Dual-Port Manometer

The SDMN5 is a portable, rugged dual-port manometer designed especially for HVAC/R field service technicians. Measures gas pressure, static pressure and pressure differential. The SDMN5 includes a zero adjust button of the face of the meter, a rugged rubber boot, a magnet on the back for hanging the meter during service, and the Auto Power-Off (APO) function conserves battery life. The SDMN5 measures pressure between -60inWC and 60inWC (inches of water column) and -150.0 to 150.0 mBar. The SDMN5 also measures P1 or P2 pressure readings and calculates the difference between P1 and P2. Take static pressure measurements using the resolution mode of 0.01inWC or 0.01mBar. Includes 3/16" to 5/16" adapter for measuring gas inlet and outlet pressures.
What's Included: Dual-Port Manometer - SDMN5, 2 - 3/16" tubes with brass fittings, 2 - 3/16" to 5/16" tube adapters - RMA316, 9V battery (installed), Operator's manual

How Does it Work?���Use the SDMN5 to measure gas pressure, static pressure and pressure differential. Simply turn it on, press the ZERO button to calibrate to ambient pressure, and then use the meter as you wish to perform the following tasks:

• Connect a single hose to get the gauge pressure relative to the ambient or ZERO pressure
• Connect both hoses if you want to see relative pressure, P1 minus P2. Select P1, P2, or P1 - P2.

Then select English (inches of water column) or Metric (mBar) units. If you are in an environment where the temperature is noticeably changing while you are taking your reading, disconnect the meter from the hoses and ZERO it relative to ambient pressure before each reading.
