GrainMate Grain Moisture Meter

Control the moisture content of grains and reduce post-harvest losses.

The Grain Moisture Meter is a tool that helps African farmers measure how much water is in their grains accurately. This is important because too much moisture can lead to mold and other problems. This new technology is affordable and easy to use, helping farmers save their crops and avoid losses.


This technology is pre-validated.

Price for resellers and users

ROI: $$$ 90 %

Post-harvest losses reduced


  • Post-harvest losses: Farmers lose grains because they don't dry them well after harvesting.
  • Difficulty measuring moisture: It's hard for farmers to check if their grains are dry enough before putting them in storage.
  • Dependence on Old Methods: Instead of using better tools, farmers rely on old and not very good methods to measure grain dryness.


  • GrainMate measures moisture: GrainMate measures how much moisture is in the grains, whether during or after drying.
  • Reducing losses: It helps farmers keep track of moisture levels, preventing losses after harvesting.
  • Accessible and easy-to-use tool: GrainMate is a tool that is easy to get and simple to use, especially helpful for farmers in sub-Saharan Africa where losing grains after harvest happens often.

  1. GrainMate Components: GrainMate is composed of a handheld reader and a probe. The probe, housing the sensor, connects to the reader through a USB cable.
  2. Moisture Measurement Process: To obtain a moisture measurement, the user inserts the probe into a sample of grain, selects the grain type, and presses the TEST button on the reader.
  3. Type Selection on Reader: Users need to choose the grain type on the reader and then press the TEST button.
  4. Data Processing: The device processes the collected data to determine the moisture content of the tested grain.
  5. Background Test: The moisture test runs in the background, and after 2-3 minutes, the moisture content is displayed on the LCD screen.
