RhizoScan is a newly designed mini-rihizotron system and is the ideal tool to investigate fine-root growth belowground through 360° scanning. RhizoScan (patented) is the first mini-rihizotron system to be fully integrated with a scanner sensor, handheld wireless control unit (i.e. no external connector cable needed), internal power supply and indexed ruler on camera handle. Using Android software (IOS and Windows APP in development) on a tablet or mobile phone you can easily adjust the scanner, control scanning operations, record and browse images. High-capacity internal batteries allow the RhizoScan systems to operate for approximately 40 hrs of active scanning time and >72 hours of additional standby time between charges. The batteries are also replacable for remote operations when additional capacity is needed.
