FIELDPIECE Digital In-Duct Psychrometer



This FIELDPIECE STA2, Digital In-Duct Psychrometer works to quickly calculate the litres per second from air velocity and free area. With the intuitive interface, the STA2 makes it easy to capture the correct data.

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.
