Electronic Manometer

The UEI EM151 Electronic Manometer is a compact pressure measurement instrument designed for gas supply and draft pressure testing in residential and light commercial applications. It provides a simple, time-saving digital alternative to traditional U-tube pressure measurements, making it practical for HVAC, gas service, heating, appliance testing and commissioning work.

The EM151 features a single pressure input with a measurement range of -20" to +20" water gauge, making it suitable for checking gas pressures, draft pressures and low-pressure system performance. It displays pressure in a triple scale, allowing technicians to read measurements in inWG, mBar and PSI.

Built for field use, the EM151 includes a rugged rubber boot with an integral magnet, allowing the meter to be mounted hands-free on suitable metal surfaces while testing. It also features simple two-button operation, 0.01" WG minimum pressure display, and auto power-off after 20 minutes to help preserve battery life.
