The meter uses a 1\/2\" (12.7 mm) diameter metal telescoping antenna sensor to detect air flows up to 2358 ft\/min and temperatures to 176°F (80°C). High accuracy is ensured with the low friction ball bearing mini-vane. Air flow can be measured in CMM (m³\/min) or CFM (ft³\/min) and temperature is selectable °F or °C. The MVT features a 4-digit LCD display, data hold, record\/recall maximum and minimum, RS232 output, averaging up to 20 measurements, 2\/3 the measured value and auto shut-off to prolong life. The unit includes telescoping mini-vane probe, hard case, 9V battery and protective rubber holster with stand.
