model, to measure air velocity, volume flow, temperature, relative humidity, and barometric
pressure. With its 1.18˝ diameter (30 mm) vane, the Series MVA is ideal for spot
measurements at air outlets. The MVA-02 is capable of detecting air flows up to 4921 ft/min
(25 m/s) and temperatures up to 140°F (60°C). The MVA-03 additionally detects humidity
from 0 to 100% with high accuracy. The MVA-04 can do all three of the above functions,
plus adds the feature of measuring absolute pressure from 10.3 to 32˝ Hg (350 to 1100
hPa). The Series MVA anemometers include a wide variety of user selectable units. These
units feature a 4-digit LCD display, data hold, ability to record maximum and minimum,
storage up to 99 air velocity records, and an auto-shutoff to prolong life. The Series MVA
also has a detachable probe for convenient replacing, if necessary. The unit includes a 6
blade mini-vane probe, nylon case, and a battery.
