RS Pro Mini Pocket Air Velocity Meter IM-740

From the trusted RS PRO brand, a mini rotating vane anemometer designed for measuring air velocity, wind speed and temperature. The digital hand-held meter provides rapid accurate readings without compromising on performance. Constructed from high-quality impact resistant materials this RS RRO pocket sized meter is ideal for engineers and HVAC technicians for on the spot measurements.

Compact in design, the RS PRO miniature anemometer features an in-built 30mm plastic impeller which registers the wind speed passing through the blades. With a measuring range of 0.4 to 20 m/s the RS PRO miniature meter can even be used for low flow speeds. In addition the RS PRO miniature anemometer is able simultaneously measure the air temperature thanks to the accurate NTC sensor.

Operation of the instrument is simple, just 4 control keys allow the user to scroll through and select the required function. The RS PRO meter displays the units for air velocity as m/s, km/h, fpm, mph, kts, and the temperature is selectable C° or °F. A large dual LCD screen clearly displays the readings and the data hold function preserves the measurements for logging purposes.
