Series MVA Mini-Vane Thermo-Anemometer

Measures Air Volume & Velocity, Temperature, Humidity and Barometric Pressure

The Series MVA Mini-Vane Thermo-Anemometer has the ability, depending on the 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.

Questions

Question
Using MVA-02 to measure fume hood vent flow. Units are set to ft/min. Area set for 6 sq. ft. Readings are incrementing by 20 units at a time, e.g. 39 to 59 to 78 to 98... Specifications indicate resolution in 1. Is this normal?
Answer
Readings that are incrementing by 20 units or so at a time, when using the MVA-02 (Mini-Vane Thermo-Anemometer), occurs when the air flow source is unstable. This is considered normal.
