Description
Coal Mine mechanical anemometer is mainly used for the measurement of the average wind speed in underground coal mines; it is also suitable for wind speed measurement in other occasions such as construction, meteorology, marine, transportation, textile, chemical industry, human defense engineering, grain processing, aerodynamic research, etc.

How to Operate
- Before measurement, close the clutch switch, press down the zero pressure lever, so that the size of the needle back to zero
- Make the rotating surface of the wind meter perpendicular to the direction of wind flow, overcome the random resistance of the running part of the meter, and make the idle rotation for 20-30 seconds first.
- Use the stopwatch to determine the time, measurement of the stopwatch and the wind speed table on at the same time, the measurement needs to be closed at the same time.
- Check the actual wind speed, according to the value read on the dial when measuring (called the indicated wind speed) in the coordinate line to check the corresponding actual wind speed value. (See calibration certificate)
Note & Remarks
- Compact size (φ70 * 42mm), simple structure, easy to carry, steel parts by heat treatment and polishing process to ensure the accuracy of the instrument, strong and durable, the dial increases, clear reading data.
- Prevent violent impact, vibration, please do not loosen the screws or open the dial at will.
- Do not touch or dial the wings to prevent the deformation and change the performance of the measured value inaccurate.
- Wipe it clean after use, put it in the box and store it in a ventilated and dry place.
- Not used for a long time, must be tested before starting, use six months to test once.
