Brilliant digital manometer for the price. I use it daily for commercial ventilation balancing. The differential pressure readings are spot on compared to my old Testo, and the backlight is a lifesaver in dark plant rooms.
Ordered on Tuesday, arrived Wednesday. It's a fantastic gas pressure tester. The 12 selectable units mean I don't have to carry multiple gauges anymore. Highly recommend to any heating engineer.
Very accurate low pressure gauge and the ±0.3% FSO resolution is great. My only minor gripe is that it uses a 9V battery rather than being USB rechargeable, but it lasts ages anyway.
Finally, a reliable alternative to the expensive premium brands. I use this hvac manometer for checking static pressure in ductwork. The silicone tubes provided fit perfectly and the zeroing function is instant.
Good solid piece of kit. It performs exactly as a digital air pressure gauge should. The soft pouch is okay, but a hard plastic case would have made it a 5-star product for throwing in the van.
I swapped out my old u gauge manometer for this digital gas manometer and I'm never looking back. Much faster to get a stable reading on domestic boiler services. Great value for money.
Operating Instructions
- Press the power button to turn on the digital manometer.
- Press the 'UNIT' button to select your required measurement (e.g., mbar for gas pressure, inH2O for air flow).
- With both ports open to ambient air, press and hold the 'HOLD/ZERO' button until the screen displays zero.
- Connect the provided silicone tubing to the positive (P1) and/or negative (P2) ports depending on whether you are measuring gauge or differential pressure.
- Connect the other end of the tubing to your test points and read the stabilised result on the backlit LCD.
Founded by former facilities maintenance engineers, ManomHVAC was born out of frustration with the UK test equipment market. We noticed that technicians were forced to choose between overpriced premium brands like Testo and TPI, or cheap, unreliable generic meters that couldn't survive a week in a toolbag.
Our mission is simple: to provide the modern UK trade with a practical, highly accurate digital gas manometer that simply works. We focus on what matters on site-reliable low-pressure measurement, a clear backlit display for dark plant rooms, and robust differential pressure capabilities for HVAC balancing and gas pressure diagnostics.
Every ManomHVAC instrument is CE and UKCA compliant, rigorously tested to deliver ±0.3% FSO resolution. Whether you are fault-finding on a domestic boiler, commissioning commercial ventilation, or conducting routine maintenance, our manometers are designed to help you work smarter, faster, and with absolute confidence.
