CID Bio-Science, Inc.

- Model CI-600 - In Situ Root Imager



Observing a root system throughout a plant’s life cycle is key to understanding overall plant behavior and health, and to improving crop performance. The CI-600 is a minirhizotron that gives plant scientists, crop consultants, and farmers the ability to capture non-destructive, high-resolution, digital images of living roots in soil over multiple growing seasons. Durable and lightweight, the CI-600 is a portable minirhizotron that is easy to transport to any field location and can be used in sites with root tubes across a range of treatments or conditions. Our free root analysis software, RootSnap!, quickly and easily calculates parameters including root length, area, volume, diameter & branching angle.

RootSnap!, our free image analysis software, allows users to measure root growth and turnover dynamics, disease, and behavior over time by analyzing scanned images collected with the CI-600. Roots are easily mapped and quantified using a multi-touch feature and our proprietary 'Snap to Root' function. RootSnap! is intuitive and efficient, using universal commands for images and file manipulation. Files are stored in common open file formats (XML) and the software supports exporting data to apps like Excel for further statistical analysis.

To obtain an image, insert the CI-600 scan head into a pre-installed underground tube and initiate a scan using the tablet computer. The scan head automatically rotates nearly 360-degrees, creating a 21.59 × 19.56 cm, high-resolution color image of the soil and roots. Users can easily move the scan head to different depths of the tube at calculated intervals using the indexing handle.

  • The CI-600 main scanner unit
  • USB connecting cable
  • Six 105cm standard clear tubes with water-tight
    end caps
  • Indexing handle
  • Operation manual
  • Calibration tube
  • Tablet computer preloaded with scanning software
    and RootSnap! imaging analysis software
