## What is 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.

The Grainmaster app lets you manage your crop stores, keep track of bale moistures and temperatures and our sample point measuring system gives you an overall view of your crops condition. 

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.

NOTE:
The Grainmaster must be on the latest firmware which can be downloaded from https://martinlishman.com/grainmaster-firmware-update/.
