Dwyer 8904 Thermo-Anemometer

The Dwyer 8904 integral vane thermo-anemometer simultaneously measures air velocity and temperature. A large 1.3″ LCD display allows users to easily view readings. Wind speed can be measured in user-selectable wind speed units including: ft/min, m/sec, knots, mph and km/hr. Additionally, a built-in sensor records ambient temperature in °F or °C. The 8904 features include data hold, the ability to record minimum, maximum and average readings on a single point and an RS-232 interface setting. The units can also record and average up to 2 hours of data while displaying the continuous running average. This compact meter is ideal for HVAC inspection, energy audits and balancing applications.
