Exceptional Data Accuracy

The H2 utilizes patented technology and innovative design to significantly enhance data accuracy. Using specialized filtering, the H2’s DSP module greatly reduces data errors caused by external factors like combine movement and ground slope to provide you with highly accurate, unbiased results. With some grain weighing systems, debris can become lodged in the weighing mechanism, or grain compaction may occur, altering the results. However, the H2 features a new, streamlined design, based on HarvestMaster’s industry-proven Classic GrainGage, which moves grain cleanly in and out of the chambers, thus proviading you with unmatched dat accuracy.

Maximized Efficiency

The H2 GrainGage allows you to collect field data more efficiently than ever. First, its patented slope and motion sensors work to provide highly accurate measurements on the go, without ever needing to stop the combine. Second, with its new design, the H2 now collects test weight, moisture, and plot weight data simultaneously, helping you get on your way to the next plot that much faster. And third, the H2’s cleaner design helps minimize maintenance, providing you with more uninterrupted work time.

Continual System Monitoring

Because we know how important your data is, the H2 has built-in mechanisms hat continually monitor the system’s operation to ensure everything is operating smoothly for the best data possible. Displays and sensors provide feedback and warnings to the operator in the case that something is not functioning properly. This assures breeders the highest quality data possible using the H2 GrainGage.
