Air Velocity Manometer

An air velocity manometer is a dual-purpose instrument designed to measure both air pressure (static pressure) and air velocity (speed). HK Calibrations provides these tools, which often use a Pitot tube to capture pressure differences and convert them into velocity readings, making them essential for HVAC duct testing and balancing.

Inclined manometers, such as the Series 424 Durablock®, feature a sloped scale that "stretches" the measurement, allowing for much higher resolution at low pressures. HK Calibrations recommends inclined models for precision work where small changes in air velocity or pressure must be detected with high accuracy.

Digital kits offer instant, high-accuracy readouts and often include features like data logging and automatic pressure-to-velocity conversion. HK Calibrations supplies these kits with all necessary accessories, including Pitot tubes and carrying cases, providing a complete "all-in-one" solution for field technicians.

Durablock® manometers are machined from solid, transparent plastic blocks, making them virtually indestructible and leak-proof. HK Calibrations offers these robust instruments because they maintain their calibration and structural integrity even in harsh industrial environments where glass or thin-walled plastic might fail.

Yes, our range includes dedicated air filter gauges like the Series 250-AF. HK Calibrations provides these to help facility managers monitor pressure drops across filters, ensuring they are replaced only when necessary to maintain system efficiency and indoor air quality.

To ensure the safety and efficiency of HVAC systems, we recommend professional calibration at least once every 12 months. HK Calibrations provides comprehensive calibration services for both liquid-column and digital manometers, ensuring your measurements remain traceable to national standards.
