Note about the scanners that we sell: Scanners sold by Regent Instruments are tested and calibrated for greater precision. All of our scanners come with software programs, some for text recognition (OCR), others for image editing and general scanning. Scanners sold by Regent Instruments are tested for their image quality and calibrated to produce accurate measurements. These scanners have been tested on roots to eliminate the problem of shadowing. The root positioning system has been designed specifically for the scanners we sell and may not work on other models.

Recommended computer configuration

Image analysis programs are extremely demanding on computer resources (more than a word processor for example), so it is a bad idea to use an old computer for this type of application. Most computers sold today have the minimal power. Although a minimum configuration can work, you will gain a lot in productivity by adding some little extras like a large screen (22"-24"), plenty of RAM (over 2GB). It works with Windows 7 to 10 (32 or 64-bit).
