Detail Dwyer Model VT-300 Thermo-Anemometer
Model VT-300 Miniature Vane Thermo-Anemometer
Telescoping Probe Measures Air Velocity, Air Volume, Temperature, and Humidity
The Model VT-300 Miniature Vane Thermo-Anemometer measures air velocity, air volume, temperature, and humidity inside air ducts. This meter includes a telescoping vane probe that is only 0.7″ (18 mm) in diameter that allows duct traverse measurements up to 20″ ducts. User-selectable units include ft/min, m/s, knots, mph, and km/hr. The vane probe has a built-in sensor to record temperature in °F or °C, as well as humidity in %RH. There are three modes which include viewing data in real time, manual recording, and automatic recording. Model VT-300 can store measurements that can later be transferred to a PC via RS-232 communication. The vane probe is detachable for easy replacement, if necessary, or as an addition to Model 9671. Each unit is supplied with a hard carrying case, batteries, logging software CD, USB to RS-232 cable and instruction manual.
