The Digi-Sense WD-37955-50 compact anemometer measures air velocity in five user selectable values: meters per second, feet per second, miles per hour, kilometers per hour, and knots with a simple one-button operation. It also allows you to measure maximum airflow, temperature (in °F and °C), and wind chill temperature with readings updated 2 times per second.

The tough ABS plastic housing and water-resistant construction keeps out moisture, dust, and dirt in harsh indoor or outdoor environments. A high contrast backlit LCD display with 3/8" digits makes it easy to read even in total darkness. Traceable products are calibrated to NIST-traceable standards and ready to use as soon as you receive it.

Each WD3795550 goes through an intense vetting process before it can carry the Traceable name, and it includes NIST-traceable certification. This means that a 17025-accredited calibration test lab has confirmed that the product meets or exceeds all stated specifications, saving you both time and money by not having to calibrate separately. NIST-traceable calibration also helps you meet quality standards and regulatory compliance for ISO, FDA, cGMP, VFC, CAP, CLIA and Joint Commission requirements.
