Portable dual port manometer accessory head for use with our modular multimeters (DMMs) and instruments. Measures gas pressure, static pressure and pressure differential. The ADMN2 includes a zero adjust and the Auto Power-Off (APO) function to conserve battery life. Disable APO for data logging. The ADMN2 measures pressure between -60inWC and 60inWC (inches of water column) and -150.0 to 150.0 mBar. The ADMN2 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.
