How to calibrate the grain moisture measuring instrument
This kind is to measure the resistance value of the grain grain, and to display the moisture content of the grain by the resistance display. The error is large, but it is convenient to use and low in price. It should be calibrated with the standard temperature test method of the electric oven. If the oven is not available, it can also be calibrated with the tunnel and other instruments. In addition, the influence of temperature is also relatively large. Based on the grain temperature of 20 degrees, the displayed value above 10 degrees will be reduced by one, and the displayed value below 10 degrees will be added by one.
