The highly accurate differential pressure meter, testo 521, with an internal pressure sensor from 0 to 100 hPa, is ideal for pitot tube measurements in the range of 5 to 100 m/s.

Differential pressure measurement on gas hot water heaters or on filters of air conditioning systems, and also flow measurements in ventilation ducts using a Pitot tube: the compact testo 510 differential pressure measuring instrument, which comes with a silicone connection hose and other useful accessories, can help you maintain and install systems in the sanitary and HVAC sector.

Match this pitot tube with a connection hose and pressure probe to allow for flow velocity measurement.

Today’s HVAC technicians want a simple solution for diagnosing ventilation issues. Differential pressure measurements only tell part of the story. Technicians also want to measure air velocity and flow, without having to resort to expensive, difficult to use, specialist tools. The Fluke 922 makes airflow measurements easy by combining three tools: differential pressure, airflow, and velocity into a single, rugged meter.

The Fluke 922 makes airflow measurements easy by combining pressure, air flow, and velocity into a single, rugged meter. Compatible with most Pitot tubes, the Fluke 922 allows technicians to conveniently enter their duct shape and dimensions for maximum measurement accuracy
