The moisture meter can quickly measure the moisture content of the grain. 1. A thermo-hygrometer is mainly used do measure changes in ambient temperature and relative humidity. 2. It can capture changes in ambient temperature and humidity at any time to make appropriate adjustments. 3. With hanging ring, suitable do temperature measurement in homes, greenhouses and warehouses. 4. It contains many air holes, which is consistent with the principle of air flow and is more suitable do atmospheric detection. 5. High accuracy of temperature and humidity measurement, with small error and long service life.
