Grain Moisture Meter

grain moisture meter is a portable device used to measure the moisture content of various grains like paddy, wheat, maize, corn, lentils, etc. It works on the principle of electrical resistance or capacitance, depending on the model.

• Sample Insertion: A small quantity of grain is placed in the meter.

• Measurement: The device measures the electrical resistance or dielectric constant of the grain sample.

• Moisture Reading: Based on pre-programmed calibration for different grain types, the device displays the moisture percentage on a digital screen.

Benefits in the Context of Bangladesh

• Reduces Post-Harvest Losses
  In Bangladesh, post-harvest losses due to improper drying and storage are significant. By using a grain moisture meter, farmers and traders can ensure grains are stored at safe moisture levels (e.g., paddy at ~14%), reducing the risk of fungal growth, spoilage, and pest attacks.

• Improves Grain Quality
  Proper moisture control ensures better grain color, texture, and overall quality, which increases its market value, especially for export.

• Better Pricing for Farmers
  Moisture content directly affects grain weight and price. Accurate readings help farmers negotiate fair prices and avoid losses from selling “wet” grains at lower rates.

• Promotes Scientific Storage Practices
  In rural areas, traditional drying methods are still used. Moisture meters introduce a more scientific approach, encouraging better drying and storage decisions.

• Time-Saving and Easy to Use
  Most modern meters are battery-operated, portable, and user-friendly—perfect for both field use and storage facilities.

• Supports Government and NGO Programs
  Many agricultural extension services in Bangladesh now recommend or distribute moisture meters to help smallholder farmers adopt better practices.
