GrainSure Pro operates at ±0.1% accuracy — the benchmark standard for professional lab equipment. Its advanced calibration system adjusts for varying grain conditions, so you get dependable results without the lab price tag or wait time.

Absolutely. For unlisted varieties, select the closest matching crop profile and apply a manual deviation adjustment within the -3% to +5% correction range. It won't be factory-calibrated, but it gives you a solid working estimate.

Four standard AA batteries power GrainSure Pro for roughly 40 to 60 hours of active testing. Heavier use of the voice broadcast feature will draw power faster, but in silent or beep mode you'll stretch life toward the higher end.

Yes. The audio output is designed to cut through typical farm and facility noise. If conditions are especially loud, switch to beep mode (d4) for a sharp audible signal, or go fully silent and rely on the bright backlit LCD display instead.

Press the adjustment key to shift readings up or down in 0.5% steps until they match your known reference. A 3-second long press resets the offset to zero. The device stores your last calibration automatically — no need to redo it each session.

Yes. The 7.5% to 50% measurement range covers the full moisture spectrum — from bone-dry stored grain all the way to freshly cut, high-moisture crop. It's equally useful at harvest, during drying, and at the storage facility.

The device retains the most recent settings, so team members should log their custom calibrations before handing the unit off. For multi-operator commercial environments, we recommend keeping a calibration reference sheet alongside the device.

With routine care, the corrosion-resistant probes are rated for thousands of test cycles. Always replace the protective cap after each use, clean the probes regularly, and insert them with steady even pressure to maximize their service life.
