8715FaceAnemometer& Product CharacteristicsWhen using the velocity matrix, you can obtain 16 points of data per square foot of cross-section at the same time, which allows you to quickly obtain the surface average wind speed. Auto-zero function eliminates manual zeroing and calibration process between readings Modular tooling for different applications and budgets Fast measurements save time Multi-line display screen for easy understanding Accurate measurements even at low flow rates Longer battery life (12 hours) and shorter recharge times TSI's LogDat software is supplied with the device for easy organization of measurement data.
The Model 8715 is a more advanced and effective version of TSI's DP-CALC series of miniature anemometers. Features and benefits include a velocity matrix for fast measurement of surface-averaged wind speeds, auto-zeroing, fast and reliable results, and the ability to make accurate measurements at low flow rates. Accurate measurements at low flow rates. Of course, the 8715 also offers the same set of benefits as the 8702/8705 anemometers: ergonomic design, data logging, automatic statistics, and more.
