TSI 8715SurfaceAnemometerProduct Features When using the velocity matrix, 16 points of data can be obtained simultaneously on each square foot of cross section, so as to quickly obtain the average wind speed of the surface Automatic zeroing function eliminates the manual zeroing and calibration process between readings Modular tools to suit different applications and budgets Fast measurement, save time Multi-line display screen, easy to understand Accurate measurement at low flow rate Longer battery life (12 hours), shorter charging time TSI's LogDat software is provided for easy data collection.
The 8715 is a more advanced and effective product in the DP-CALC series of micro wind pressure gauges from TSI. Its features and advantages include a velocity matrix that can quickly measure the average wind speed on the surface, automatic zeroing, fast and reliable measurement results, and accurate measurement at low flow rates. Of course, the 8715 also has a series of advantages of the 8702/8705 wind pressure gauges: ergonomic design, data recording, automatic statistics function, etc.
When using the velocity matrix, 16 points of data can be obtained simultaneously on each square foot of the cross section, so as to quickly obtain the average wind speed on the surface. The automatic return to zero function eliminates the manual zeroing and calibration process between readings. Modular tools are suitable for different applications and budgets. Fast measurement saves time. The multi-line display screen is easy to understand. It can still accurately measure at low flow. Longer battery life (12 hours) and shorter charging time. TSI's LogDat software is randomly provided to facilitate the collation of measurement data.
