The Air Pro 0 to 500 Pa differential pressure gauge is a mechanical diaphragm gauge designed for HVAC and cleanroom service, including across-filter monitoring, room pressurization verification, and AHU coil pressure-drop measurement. It is rated to 15 PSI (1.03 bar) static pressure with a measurement range of -68 to 103 kPa.

Accuracy is specified at +/-2% of full scale on standard ranges, with +/-3% on -0 and +/-4% on -00 variants. The unit is housed in a grey enclosure weighing 0.55 kg and is qualified for an ambient operating temperature window of -7 to 60 degrees C, making it suitable for plant rooms, ceiling voids, and clean utility panels.
