FEATURES

Roast Colour Measurement: Measure roast colour with ±0.5 precision to help maintain consistency from batch to batch with reliable, repeatable results.

Utilises a single-point near-infrared sensor to obtain an average colour reading of the whole sample; for a full colour distribution histogram, check out the DiFluid Omni or Omix.
