The AM-4200 Digital Anemometer is a versatile and professional instrument engineered for accurately measuring air velocity and wind speeds in a wide variety of environments. Built with a precision low-friction ball vane sensor and a robust ABS housing, the AM-4200 ensures reliable data collection whether you’re on the shop floor, performing HVAC system diagnostics, conducting environmental studies, or carrying out laboratory experiments.
This compact device features an independent sensor probe for safe and convenient remote readings, allowing you to access tight or hard-to-reach areas without compromising measurement accuracy. The large 13mm (0.5") LCD screen provides clear, easily readable results in multiple selectable units—including meters per second, kilometers per hour, knots, and feet per minute—making it perfect for professionals who need quick conversions at a glance.
Designed for user-friendliness, the AM-4200 operates on a standard 9V battery and can deliver up to several hours of continuous use in the field. Its quick sampling time (roughly 0.4 seconds) means instant results, saving valuable time during inspections and site surveys. The lightweight construction (381g including battery) further enhances portability, so you can easily carry it wherever precise airflow or wind measurement is needed.
