Q1: How does a moisture meter work?
A1: The portable moisture detector is composed of a capacitance sensor, C/V conversion circuit, A/D converter and LCD digital display circuit. After the capacitance sensor is scooped into the tested grain, the medium is a variety of different grains tested. Since the dielectric constant of water is much larger than that of general substances, a small change in the measured grain water content will cause a large change in the capacitance of the sensor. Through the C/V conversion circuit and A/D converter, the LCD digital circuit directly shows the percentage of the measured grain water content.
Q2: What are the types of moisture meters?
A2: A moisture meter (moisture tester) is a measuring instrument for moisture content that can quickly determine the moisture content of a substance. Commonly used moisture meters include chemical moisture meters, paper moisture meters, infrared moisture meters, grain moisture meters, building materials moisture meters, mortar moisture meters, crack moisture meters, soil moisture meters and wood moisture meters.
Q3: Why need a digital grain moisture meter?
A3: Moisture content is one of the most important indexes in the pricing, quality evaluation and storage of grain purchase. Accurate measurement of water content before grain storage can effectively prevent the adulteration of suppliers. The moisture content measurement of grain before warehousing can effectively grasp the status quo of grain in the storehouse and prevent the occurrence of moldy and bad materials in the storehouse.
A portable grain moisture meter is a high-precision moisture detector, it can be the real-time measurement of the whole package of grain moisture, and can be measured in kinds of grains, including wheat, flax, corn, paddy, and oats.
Tips: What is a pin-type moisture meter?
The pin-type moisture meter is suitable for the rapid determination of the percent moisture content of the grain, corn, rice, wheat, soybean, etc. The principle is that the product adopts single-chip computer chip technology, with 7 sets of correction gears, and the double needle contacts the surface temperature of the original grain. . Detect the initial moisture of the raw grain in the contact space range. Because of its relatively cheap price, it is generally accepted by farmers, and the moisture content of the raw grains (corn, barley) tested generally ranges from 18-20%.
