Grainmaster i2-S

Professional grain moisture measurement

Protimeter grainmaster i2-s grinder compressor unit

Built on the foundations of the UK’s most popular moisture meter, the Protimeter 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 Protimeter Grainmaster i2-S give high levels of repeatability between samples. As a grinding moisture meter you can also be confident that readings will record grain moisture accurately throughout each sample.
