TSI® VelociCalc® Air Velocity Meters

Each model has an extended velocity range of 0–6000 ft. / min. and a temperature range of 0°–140°F or more. The 37"L telescoping probe has etched lengths to make duct traverse measurements much easier while the sample function easily records multiple measuring points. Flowrate feature gives simple and quick calculations of volumetric flowrate—all you have to do is input the shape and size of the duct. Air Velocity / Humidity Meters (Nos. 113374 and 113379) have a 0–95% humidity range and feature direct calculation of dew point and wet bulb temperature. Requires no psychrometric chart. Air Velocity Meters (Nos. 113379 and 70972) have an articulating probe to make it easier for you to measure ceiling outlet flows or clean benches. Each includes four AA batteries.
