Moisture content, oil content, nitrogen levels and specific weight are analysed using a specific piece of equipment called the Infratec. As this is used to test every load that comes into or leaves Wiltshire Grain its accuracy is vital. In order to ensure accuracy, we belong to the UK NIR Grain Network.  

All machines belonging to the network are calibrated before harvest and calibrations made remotely by engineers through electronic updates. Once a month test samples are sent to network members as a ring check to ensure all equipment remains correctly calibrated.
