Narrow Gauge Root Imager

A New Minirhizotron System Compatible with 2-inch Diameter Tubes!

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-602 Narrow Gauge Root Imager is a minirhizotron system that captures non-destructive, high-resolution, digital images of living roots in soil over multiple growing seasons. Compatible with root tubes measuring two inches in diameter, the CI-602 gives users the ability to work within new and existing tube installations.

The CI-602 is a durable and lightweight 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.
