Hi-Res Differential Manometer

The UEI EM201B Hi-Res Differential Manometer is a professional pressure testing instrument designed for HVAC, gas service, heating, appliance testing and light commercial diagnostics. It provides a simple digital alternative to traditional U-tube manometers and is ideal for measuring gas supply pressure, draft pressure and pressure drops across equipment.

With dual pressure inputs and differential pressure measurement, the EM201B allows technicians to compare pressure between two points quickly and accurately. It measures pressure up to ±60 inH₂O, making it suitable for a wide range of low-pressure HVAC and gas applications. The hi-resolution display helps provide detailed readings for commissioning, servicing and fault finding.

Built for field use, the EM201B includes practical functions such as backlight, Hold, Min/Max, Zero, selectable units, auto power off, protective overmoulding and a magnetic mount for hands-free use on metal surfaces. It is supplied with a 9V battery and pressure tubing, and is backed by a 3-year limited warranty.
