The Extech 45168CP is a pocket-sized Mini Thermo-Anemometer with a built-in compass, designed to combine windspeed measurement, environmental readings, and directional information in a single handheld instrument. The unit folds for storage and extends up to 9 inches when taking measurements, and its housing is water resistant, floats, and is drop-tested to 6 feet for use in demanding field conditions.

The 45168CP measures windspeed across six units — feet per minute, meters per second, kilometers per hour, miles per hour, knots, and Beaufort Force — with a 10-second averaging function and a Max recall for the highest reading captured over time. Beyond windspeed, the instrument provides Temperature, Relative Humidity, Dew Point, Wet Bulb, and Windchill, along with a Delta T display showing Air Temperature minus Dew Point. The built-in compass provides 360° wind direction readings and supports Head, Cross, and Tail Wind calculation, with a user calibration procedure for improved accuracy.

ValueTronics has supplied test and measurement equipment to engineers, technicians, and field professionals since 1992. Each instrument we sell — including handheld environmental meters like the Extech 45168CP — is stored and tested in our 20,000 square foot secure warehouse at 1675 Cambridge Drive, Elgin, Illinois, so you receive an instrument that has been verified before it ships rather than passed through from an anonymous source. This is the difference between buying from a distributor with a physical operation and buying from a drop-shipper or marketplace listing.

## Brand Heritage

**Important:** Windspeed range begins at 60 ft/min (1.1 m/s) — measurements below this threshold fall outside the rated range.Recommended pairing: keep the 45156 Spare Mini Impeller Assembly (2-pack) on hand — the impeller is replaceable by design, and a spare prevents downtime if the vane is damaged in the field.
