Extech 45158 Mini Thermo Anemometer with Humidity
Measure air velocity, temperature, relatve humidity, dew point and wind chills levels with this pocket-sized, waterproof digital anemometer from Extech.
Featruing a built-in vane sensor, the Extech 45158 can measure both air velocity and temperature/relative humidity (or wind chill) simultaneously and show results on the built-in LCD screen. It can be used to measure wind speed in feet per minute, miles per hour, metres per second, kilometres per hour, knots and Beaufort force.
The Extech 45158 anemometer has a uniquely designed case - it can be flipped open to extend the reach of the anemometer up to 9" (ideal for those applications which are just out of reach) and can be snapped shut when done testing for pocket-sized storage. The built-in vane sensor is made of plastic and can be replaced if needed at a later date.
This anemometer also includes several additional features: a data hold facility freezes the current display and it's also made tough - the Extech 45158 anemometer is water-resistant and floats in water and it can even be dropped from a height of up to 6 feet and keep on working.
