Built for the Field. Trusted in the Lab.
Reads Within 0.5% of Your Elevator
Temperature-compensated capacitance delivers reliable repeatability. Farmers consistently stay within 0.5 points of their buyer tester each season.
One Device, 14 Crops
Pre-calibrated profiles for corn, wheat, rice, soybeans, peanuts, and nine more varieties are ready at the tap of a button. Replace a cabinet full of single-crop testers with a single, field-ready tool.
Settings That Never Forget
Unlike generics that drift within months, persistent memory holds your calibration. Harvest after harvest starts right where you left off.
Rugged, Field-Ready Build
Corrosion-resistant construction handles dust, vibration, and field temperature swings. Farmers report running similar builds for 8-12 years.

Frequently Asked Questions
How does GrainSure Pro compare to actual laboratory moisture testers?
How does GrainSure Pro compare to actual laboratory moisture testers?
GrainSure Pro uses temperature-compensated capacitance validated by elevators and universities. Real-world accuracy in the 10-25% moisture range is +/-0.5% vs. the oven method, and thousands of farmers stay within 0.5 points of their buyer tester.
Can I test grain types that aren't among the 14 pre-calibrated varieties?
Can I test grain types that aren't among the 14 pre-calibrated varieties?
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.
Does grain temperature affect the reading — do I need to let cold grain warm up first?
Does grain temperature affect the reading — do I need to let cold grain warm up first?
GrainSure Pro built-in compensation corrects for temperature automatically. One caution: grain pulled from a cold bin into a warm room can develop surface condensation, so test before it changes temperature for the most reliable reading.
Will the voice broadcast be audible on a noisy harvest floor or in the field?
Will the voice broadcast be audible on a noisy harvest floor or in the field?
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.
How do I calibrate the device for a specific grain batch or temperature?
How do I calibrate the device for a specific grain batch or temperature?
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.
Is GrainSure Pro suitable for testing both freshly harvested and dry stored grain?
Is GrainSure Pro suitable for testing both freshly harvested and dry stored grain?
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.
How do I get a representative sample — does it matter where I take it from?
How do I get a representative sample — does it matter where I take it from?
Moisture varies within a load, so grab 3-5 subsamples from different depths and let GrainSure Pro average the results. One scoop from a corner can be 1-2 points off the true load average. Cracked kernels read drier; use clean, whole grain.
What's the difference between a capacitance meter and testers that grind or crack the grain?
What's the difference between a capacitance meter and testers that grind or crack the grain?
Grind-type testers crack grain first, adding error from damage and dust. GrainSure Pro passes a low-power signal through an intact sample — water alters the electrical charge differently than dry starch, so moisture is read without destroying it.
