Why Choose ManomHVAC
The Ultimate Digital Pressure Gauge for the Trade
The ManomHVAC Pro is a heavy-duty digital manometer engineered specifically for British HVAC professionals and maintenance engineers. Moving away from fragile analogue u gauge manometers, this handheld device provides instant, highly accurate readings for air and gas pressure testing. Whether you're checking static pressure in ductwork or fault-finding on a heating system, this instrument delivers the reliability you need without the premium brand markup.
Precision Differential Pressure Gauge
Equipped with dual ports, this meter excels as a differential pressure gauge. It features an advanced piezoelectric sensor that guarantees ±0.3% FSO resolution at 25°C. With 12 selectable units-including mbar, kPa, psi, and inH2O-you can seamlessly switch between metrics depending on the specific HVAC manometer task at hand. The clear, backlit LCD ensures that your readings are always visible, even in the darkest boiler rooms or ceiling voids.
Field-Ready and Efficient
Designed for life in a toolbag, this digital air pressure gauge features a rugged housing and an intuitive interface. The auto-off function preserves battery life during long shifts, while the simple zero-calibration button ensures accuracy before every manometer test. It's the definitive low pressure gauge for professionals who demand speed, accuracy, and durability on site.

Customer Reviews
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.
Excellent manometer test instrument. The build quality feels rugged enough for site work. The screen is large and easy to read, even when you're squeezed into an awkward airing cupboard.
