TSI® VelociCalc™ Air Velocity/Humidity Meters

Calculate Flow Rate, Averages, and So Much More!

With a few simple keystrokes, you can make all the necessary calculations quickly and easily, measure air velocity, temperature, multi-value averaging and minimum/maximum values.
Specifications: Each model has an extended velocity range of 0 - 6000 ft./min. and a temperature range of 0° - 140°F or more. The 37" telescoping probe has etched lengths to make duct traverse measurements much easier while the sample function easily records multiple measuring points. Variable time-constant modes give a steady display when measuring fluctuating flows. Flowrate feature gives simple and quick calculations of volumetric flowrate, all you have to do is input the shape and size of the duct. Nos. 113374 and 113379 have a 0 - 95% humidity range and feature direct calculation of dew point and web bulb temperature. Requires no psychrometric chart. Nos. 113379 and 70972 have an Articulating Probe to make it easier for you to measure ceiling outlet flows or clean benches. Includes four AA batteries.
