Operating Instructions

How to use
  1. Ensure the unit is powered off, then connect the flexible hoses to the positive (P1) and/or negative (P2) ports depending on your test requirement.
  2. Power on the manometer and press the 'ZERO' button to calibrate the gauge to ambient atmospheric pressure.
  3. Select your desired measurement unit (e.g., mbar for gas valves) using the 'UNIT' button.
  4. Connect the hoses to your test points (e.g., boiler test nipple or ventilation duct).
  5. Read the digital display for an accurate differential pressure measurement. Use the 'HOLD' function to freeze the reading if required.

Brilliant piece of kit. Replaced my old analogue u gauge manometer with this. The mbar readings are spot on for checking gas valves on combi boilers. Saves me loads of time.

Excellent gas pressure tester. The backlit screen is a lifesaver in dark airing cupboards. Highly recommend for any Gas Safe engineer.

Very accurate differential pressure gauge for HVAC work. The zeroing function is quick. Only dropped a star because the supplied hoses could be a bit longer, but standard tubing fits fine.

I use this digital manometer for automotive diagnostic work, checking DPF pressures. It's robust, easy to read, and the unit selection is very handy.

Ian Robertson, Glasgow

Great value for money compared to the big name brands. The accuracy is just as good, and it feels solid enough for daily van use.

Good air pressure meter. Simple to use and the hold function is useful when you're stretched awkwardly to reach a test point. Battery life seems decent so far.
