The Extech 45158 keeps you ready for sudden shifts in air flow or heat. It reads wind speed and temperature at the same time, and then shows wind chill when you need it most. The pocket body is sealed against water, so light rain will not slow you down.
Performance in Any Weather
Because the Extech 45158 measures from 1.1 to 20 metres per second, it works for both gentle room vents and open-field gusts. Its 5, 10, or 13-second averaging keeps the read-out steady, yet the fast screen still reacts to quick bursts.
Built for Field Work
The folding handle stretches to 229 millimetres to clear hoods and grills, and the rear thread lets you fix the Extech 45158 to a tripod for repeat tests. The keypad gives you Hold to freeze the reading and Auto Off to guard the cell.
Swap units between m/s, km/h, ft/min, mph, knots, and Beaufort, and see the clear LCD in bright or low light. With its light frame, the Extech 45158 hangs from the supplied lanyard and slips back into a work pocket without fuss.
