The Grain Moisture Meter (DMM & DMA Series) is a reliable digital instrument used to measure moisture content in grains, pulses, seeds, spices, dry fruits, and animal feed. These impedance-type meters work on the principle of measuring the dielectric constant of materials, ensuring high accuracy and consistency.
Built with a rugged ABS moulded body, the device is suitable for long-term field use and is calibrated as per IS-8824-Part-1-1978 standards. It comes with auto temperature compensation and supports multipoint calibration, making it ideal for farmers, traders, warehouses, food processors, and quality inspectors.
The DMM models provide manual calibration, while the DMA series comes with auto calibration and more advanced features for higher accuracy.
