GM8909 Digital Handheld Anemometer High Precision Air Volume Tester Wind Meter

• Anemometer  GM8909  is a professional measuring device equipped with a sensitive remote impeller for measurements in hard to reach places. In real time can measure the speed, volume and temperature of the air flow. Anemometer  GM8909 is  very easy to operate and reliable. The case of the device is protected by a rubber protective cover. A distinctive feature of the model  GM8909  is the presence of a sliding telescopic handle, which facilitates work in hard to reach places.

Features:

1. Anemometer  GM8909 is  equipped with a remote impeller to measure the speed and temperature of the air flow in hard to reach places
2. Sliding telescopic handle – increases the possibility of operating the device in hard to reach places
3. Big range of measurement of speed of an air stream: 0,3-45 m / s
4. Dustproof and waterproof case in a rubber case to protect against shock
5. Air temperature measurement
6. A distinctive feature of this model is a very sensitive impeller on a  bearing mechanism  (in most budget models of anemometers, the impeller rotates in oil, and therefore the accuracy drops at negative temperatures for such anemometers). With the GM8909  anemometer  you can be sure of the accuracy of measurements in a wide range of temperatures.
7. Display backlight
8. Low battery indication
9. Display of maximum, minimum, average and current speed values
10. Auto power off
