Model VT-300 Miniature Vane Thermo-Anemometer

Specifications - Installation and Operating Instructions

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 OT (18 mm) in diameter that allows duct

traverse measurements up to 20· ducts User-selectable units include ft/min mis

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
