MC 4.0 Vane Anemometer
The MC 4.0 anemometer is suitable for determining the flow velocity, temperature and relative humidity of gaseous and liquid media. The measurement with a vane anemometer is considered to be the most accurate of the possible measurement methods. As a further bonus, the periodic calibration of the MC 4.0 only requires the renewal of the measuring heads. This means that the device does not need to be sent in as with comparable products. The areas of application include flow measurements, flow measurements, filter monitoring, exhaust and supply air controls, volume flow measurements and much more.Plastic sensors can be used for non-aggressive gases or liquids. Steel sensors are suitable for use in aggressive media.Including logger function and the option of connecting 2 sensors.Connections:2 Lemo Connectors & 2 USB-C connections or 4 USB-C plugs as digital versionDisplay 3,2" TFT-Display, optional with Touch-Funktion (resistive)Measuring rate 2 measures / sPower Supply Lithium-Polymer-BatteryOperating life per battery charge approx. 15 hours (4000mAh)Housing dimensions (LxWxH)168 x 68 x 38  mmProtection IP 67Weight approx. 300 grammOperating temperature 0 to 60 °CHumidity 0 to 99 % rHProtection case Removable rubber case in blue, red, green and orangeMeasuring media: dry instrument air or inert gasesUnits of measurement: Velocitiy: m/s, km/h, ft/s, mph Pressure: Pa / kPa, mbar, mmH2O: Flow: m/sMeasuring rate: 2 measurements / sec.Volume flow: m³/h, l/min, m³/s, cfm
