  • Collect a Representative Sample: Take subsamples from multiple depths or spots in the load — one scoop from one corner is the #1 source of bad readings. More locations, more accuracy.
  • Test and Average: Pour your sample into the test cell and run 3+ readings. GrainSure Pro averages them automatically, canceling out any one-off kernel or hot spot that would fool a single-sample meter.
  • Read, Listen, and Act: Your moisture result appears on the backlit LCD in seconds — voice broadcast announces it aloud so your hands stay free. If it crosses your preset threshold, an audible alert fires before damage sets in.

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.

GrainSure Pro

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

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.

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.

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.

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.

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.

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.

Collect subsamples from several depths or spots in the load, pour a sample into the test cell and run several readings. GrainSure Pro averages them and shows the result on its backlit LCD.

Farmers use a grain moisture tester to check moisture in crops such as corn, wheat, rice, soybeans and peanuts at harvest, during drying and in storage. GrainSure Pro also sounds an audible alert at a preset threshold.

GrainSure Pro: A Grain Moisture Tester for Harvest and Storage

GrainSure Pro is a grain moisture tester for farmers who check crops at harvest, during drying and in the bin. It uses temperature-compensated capacitance and holds 14 pre-calibrated crop profiles, including corn, wheat, rice, soybeans and peanuts.

As a corn moisture tester, it takes a sample poured into the test cell and averages several readings automatically. The result appears on a backlit LCD, and a voice broadcast announces it aloud so hands stay free.

Persistent memory keeps calibration settings between seasons, and a preset threshold triggers an audible alert. Corrosion-resistant construction suits field use. This grain moisture meter ships with a protective probe cap and user manual.

  • Moisture meter for corn and 13 other crops
  • Backlit LCD display
  • Audible threshold alert
