I. Product Introduction The LKS-7 Portable Stick Moisture Analyzer uses the direct shovel method to determine the moisture content of grain. Easy to operate, test quickly, intuitive readings, easy to carry. It is an ideal equipment for the purchase of grain that is scheduled to be used for grain storage monitoring.

5. Power 6F22 stacked battery one (9V)

6. Overall size (mm)

7. Weight: 0.5kg

Third, the working principle of the instrument by the capacitive sensor, C / V conversion circuit, A / D converter and LCD digital display circuit. Capacitive sensor shovel into the measured food, the media is measured in a variety of different food. Since the dielectric constant of water is much larger than the dielectric constant of a general substance, as long as there is a slight change in the moisture content of the measured grain, it will cause a large change in the sensor capacitance. Through the C/V conversion circuit and the A/D converter, the LCD digital circuit directly displays the percentage of water content in the measured grain.
