While optimized for 14 varieties, you can test other grains using similar crop settings and applying manual calibration adjustments. The -3% to +5% deviation range allows customization for unlisted varieties with reasonable accuracy.

Four AA batteries typically provide 40-60 hours of continuous operation depending on voice broadcast usage. Battery operation eliminates power cord constraints, enabling extended field testing without interruption or recharging delays.

Yes, the voice broadcast system delivers clear audio announcements audible in typical agricultural environments. You can also select bip-sound mode (d4) for noisy settings or switch to silent mode while relying on the backlit LCD display.

Use the adjustment key to fine-tune readings in 0.5% increments based on grain temperature and condition. Long press for 3 seconds resets to 0%. Smart memory retains your calibrations automatically for consistent future measurements.

The wide 7.5% to 50% measuring range handles both dry storage grains and freshly harvested wet crops. This versatility makes the Hygromux ideal for testing throughout harvest, drying, storage, and processing stages.

Smart memory function stores the most recent settings, but users should record their custom calibrations. For shared devices in commercial settings, establish standard protocols or maintain calibration logs for different operators and grain types.

The corrosion-resistant metal probes withstand thousands of tests with proper care. The included protective cap prevents damage between uses. Regular cleaning and avoiding excessive force during insertion ensure years of reliable probe performance.
