Elevator-Grade Accuracy

  • USDA & CGC Calibrations: Stop guessing. The MINI-405 uses the same crop calibrations as the elevators, including specific settings for High/Low Moisture Corn, Soybeans, and all Wheat types.

  • Deep-Kernel Sensing: Most portable testers only "skim" the surface. Our high-frequency technology penetrates deep into the kernel for a true moisture reading, not just a surface estimate.

  • Precision Temperature Compensation: Whether it’s -10C or 66C (14F–150F) outside, the built-in thermometer and 200g calibration weight ensure your readings are dead-on every time.

The "Hot Grain" Advantage “Why Wait”

  • Test Straight From the Dryer: No more waiting 20 minutes for samples to cool. Pull corn directly from the dryer and get a professional-grade reading instantly.

  • Heat-Sync Technology: The MINI-405 doesn’t just "handle" the heat—it accounts for it. The system automatically adjusts moisture calculations for hot grain up to 150F.

Smart Farm Integration

  • Sync to Your Smartphone: The Units talk to your phone via the mobile app, allowing you to save, track, and share up to 500 results instantly.

  • Your "Field Scout" for Bins: Use the Portable units  at the combine or auger to scout your grain. Use that real-time data to decide exactly where to store it and how to program your automated fan systems.

Built for the Field

  • "Truck-Proof" Durability: Built for the cab, not the office. The portable units come in a rugged, foam-lined carrying case designed to live in your pickup or tractor without losing calibration.

  • Over-the-Air Updates: Never send your unit to a shop for updates again. With built-in Wi-Fi, the Units receive the latest software and crop calibrations automatically from anywhere.
