在RINNTECH我们多年的经验和多项专利的用户和开发领域中的树木和木材分析
Since the late 1980s, Frank Rinn’s name has been inextricably associated with the RESISTOGRAPH®, the world’s first hand-held measuring unit that precisely detects the inner condition of trees and wood. His innovative work has been crowned with numerous awards (1989, 1992, 1997 and 1998). Many of the devices developed by him have been patent-protected. 
 At RINNTECH we have many years of experience and numerous patents as users and developers in the field of tree and wood analysis.
