Moisture Measurement for the Grain Store

Professional Crop Moisture Measurement

For the Grain Store

The new Grainmaster i2

Built on the foundations of the UK’s most popular moisture meter, the Grainmaster i2 offers the same accurate moisture measurement with new enhancements.

Accurate moisture measurement is critical at harvest time and throughout drying and storage. So it makes sense to use a meter that has a track record for providing consistent, accurate and reliable grain moisture readings.

Using tried and tested crop calibrations, the robust electronics of the Grainmaster i2-S give high levels of repeatability between samples. As a grinding moisture meter you can also be confident that readings will record moisture accurately throughout each sample.
