The STA2 is a Hot-wire Anemometer built for the HVACR professionals' air balancing needs. The compact probe tip makes measuring air velocity directly in the duct a breeze. It's great for traversing a duct and automatically calculating l\s without the hassle and expense of a bulky hood. The 950mm telescoping probe's laser etched ruling and flattened edges allows techs to locate proper measurement points within a duct, and ensures that the probe is properly aligned.
This in duct hot-wire anemometer quickly calculates litres per second [l\s] from air velocity and free area. With the intuitive interface, the STA2 makes it easy to capture the correct data.
