Types of Grain Moisture Meters

A grain moisture meter is a device used to measure the moisture content in grains such as maize, rice, wheat, beans, millet, and sorghum. It helps farmers, traders, and millers determine whether the grain is dry enough for harvesting, storage, or sale, helping to prevent spoilage, Mold, and weight loss.


🔧 How It Works:

  • The meter uses electrical resistance, capacitance, or infrared heat to assess how much water is in a sample of grain.
  • Some require you to insert a probe into the grain or pour a sample into a test chamber.
  • Results are usually displayed on a digital screen as a percentage of moisture (e.g., 13.5%).

Why It’s Important:

  • Too much moisture can cause grains to rot or grow fungus.
  • Too little moisture can lead to weight loss and reduced profits.
  • Helps meet market standards for safe grain storage and export.

Grain moisture meters are essential for post-harvest quality control and maximizing profits.

Types of Grain Moisture Meters

Grain moisture meters come in several types, each with unique features suited to different environments and accuracy needs:

Portable/Handheld Moisture Meters

Description: Compact, battery-operated devices used directly in the field or storage.
How it works: Insert grain into the built-in chamber or attach a probe.
Best for: Farmers, small-scale traders
Examples: GMM mini, Farmex MT-PRO
Pros: Easy to carry, quick results
Cons: Slightly less accurate than lab-grade models


2. Pin-Type Moisture Meters

Description: Use sharp metal pins/probes to penetrate grain or grain bags.
How it works: Measures electrical resistance between pins, which varies with moisture.
Best for: Bagged grains, deep sampling GM640
Pros: Good for stored grain
Cons: Can damage samples slightly


3. Capacitance-Type Moisture Meters

Description: Use a sample chamber to measure changes in electrical capacitance.
How it works: Grain is poured into the chamber; meter reads moisture via dielectric properties.
Best for: Accurate, repeatable results on various grains
Pros: High precision, suitable for different grain types
Cons: More expensive than basic models


4. Infrared Moisture Meters

Description: Use heat and infrared to determine moisture by drying the sample.
How it works: Measures weight loss from moisture evaporation
Best for: Laboratory or industrial use
Pros: Highly accurate
Cons: Slower and costlier; not field-portable


5. Online/Continuous Moisture Meters

Description: Installed on grain processing lines or silos for real-time monitoring.
How it works: Continuously measures grain moisture as it flows
Best for: Grain processing plants, mills
Pros: No manual input, consistent tracking
Cons: Requires professional setup and calibration


6. Universal/Grain-Type Selectable Meters

Description: Digital meters with settings for multiple grain types (maize, rice, wheat, etc.)
How it works: User selects grain type from the menu for specific calibration
Best for: Multi-crop farmers and traders Draminski GMM mini Pro
Pros: Versatile, saves time
Cons: Requires proper calibration for accuracy
