Our NIR Machines:

  • Totally modular and unlike x-rays systems, a single unit can be as wide (or narrow) as required
  • Unlike x-rays tubes, our easily replaced detector cassetes (spare unit supplied) ensure zero downtime and continuity of production
  • Can be easily retrofitted into HACCP points in existing production lines
  • Completely non-ionising with zero safety compliance issues
  • Permanently record all inspections
  • Have full internal capacity for continuous detection software upgrades
  • Allow for remote internet control of system settings and parameters by our engineers
  • Have the capacity to alert management via SMS text message/email on detection of defect

Some of Our Applications

Our patented Near Infrared (NIR) inline inspection machines detect contaminants which x-rays and metal detectors can not easily see in food stuffs an in various industrial products. We can see;

  • Wood
  • Plastic
  • Rubber
  • Paper
  • Stones & Pits

Cascaded Detectors to Increase Detection Rates

Efficiency of the NIR system can be improved by sequentially cascading separate NIR detectors and using the combined results of both to produce a single measurement.

Introducing the appropriate number of sequential detectors for a specific application produces minimum requirement of 95% detection rates.

If properly configured, overall false positive rates are typically around 3%.
