Digi-Sense’s 20250-15 Professional CFM/CMM Vane Thermoanemometer is crafted for air velocity and airflow measurements that are precise and accurate. The 20250-15 allows for user versatility by providing the option to choose from 7 units of measurement: ft/min, m/s, mph, km/h, knots, CFM, and CMM.
Digi-Sense has outfitted the 20250-15 with a variety of features for proficiency like the expansive dual display which concurrently shows air velocity or airflow and air temperature. The thermoanemometer enables air velocity, airflow and temperature parameters to be measured on a single point, average, maximum or minimum basis. Even more, users can save time with the available 16 memory storage locations (8 CFM and 8 CMM) for frequently tested air vent sizes. The 20250-15 comes supplied with a foam-cut hard protective carrying case for a total value.
Included:
vane probe sensor with 3.9-ft (1.2-m) cable, hard carrying case, and one 9 V battery.
