Custom Model Building


In some situations, a custom model is not just the best option, but the only effectivesolution. Here’s why:

  • OptimizePacking Efficiency

Acustom NIR model enables you to accurately assess product maturity andreadiness before shipping, ensuring that only top-quality produce reaches retailers.

  • EvaluateNew Crops

Without a clear maturity standard, harvesting can be uncertain and inconsistent. Acustom NIR model provides precise, reliable data to guide confident and timelydecisions.

  • Adaptto Specific Cultivars or Regions

Evenfor well-established crops, different cultivars or growing regions often require unique bench marks. A tailored model ensures that your measurements align with your exact needs and growing conditions.
