Anemometer – ET-101
The ET-101 is a wireless, self-powered anemometer that can be used in fountain and water feature, crane and construction, and nautical applications. It is a highly reliable, low maintenance option for wind measurement.
Installing the ET-101 is simple and straight forward. Because the anemometer is wireless you won’t have the expense and effort of wiring the unit to the control display. The threat of lightening damage to the control display is also eliminated without a wired application. An internal generator provides all necessary power and eliminates battery replacement maintenance that some anemometers require.
