The Extech HD350 Pitot Tube Anemometer + Differential Manometer provides simultaneous display of pressure, air velocity or air flow, and temperature readings in a single instrument. It offers a ±0.7252 psi pressure range with 5 selectable units of pressure measurement, supporting versatile industrial and HVAC measurement applications.

This meter includes a comprehensive set of functions: max/min/avg recording, relative time stamp, data hold, and auto power off. It features a large backlit LCD for clear readability in various environments, a zero function for offset correction or baseline measurement, and a USB port for data communication. The HD350 can store and recall up to 99 readings in each operating mode, supporting convenient on-site data recording and post-analysis.
