Low differential pressure measurement instrument for monitoring and testing draft pressures such as duct air pressure in a HVAC system. Connect the pressure monitor across a venturi plate, air filter, ventilation fan or pitot air probe to measure the differential pressure drop generated by the air flow.
Hand-held portable manometer for measuring positive and negative pressure ranges from 25 mbar up to 10 bar gauge or differential plus a 2 bar absolute. The measurement accuracy is 0.15% reading + 0.15% fs + 1 digit over a temperature range of -10 to +50°C. Optional leak detection, data logging and averaging filter functions.
