RINNTECH RESISTOGRAPH R650 series

The RINNTECH RESISTOGRAPH is a resistance drill for the inspection of trees and timber condition. A precision resistance drill, the RINNTECH RESISTOGRAPH matches the feed rate and drilling speed to the actual wood condition. By matching the drill speed and feed rate, the RINNTECH RESITOGRAPH provides a 1:1 scale printed reading via the included printer of the tree or timber density in realtime. In addition, the use of an Android device, with the RINNTECH app, allows for GPS location data to be included along with the profile. Additionally, the data is stored internally on the RESITOGRAPH for evaluation on a PC with the DECOM software. These features become an essential tool for professional arborists to detect the inner condition of trees or wooden structures. There are two models available for Australian, New Zealand and South-East Asia arborists and consultants:

• R650-ED: RESISTOGRAPH Series 6, High Density (tropical) hardwoods Especially suited for examination of extremely dense (tropical) hardwoods
• R650-SC: RESISTOGRAPH Series 6. Scientific 2D/3D research version (24 Sensors) For scientific analysis: maximum possible resolution and precision. Also used for climate change research.  It can be calibrated and used to determine wood density (R² = 0.96).

Recommended Software for Resistograph

Users can download a free of charge mobile app called RESISTOGRAPH® from the Google Play Store. This mobile app provides simultaneous real-time profile display, storage and transmission of data, and (optionally) remote control of the machine. The app also records the GPS location.

DECOM™

The DECOM™ software allows you to display trees’ profiles can be displayed on the screen or printed as a graphic chart, and can be processed for your reports. Mathematical and statistical routines are available for scientific applications, such as trend adjustments, tree ring detection, etc.

Applications

• Tree check-ups
• Increment analyses
• Quality assessment of forest trees
• Wood analyses

Benefits

• Online recording of RESISTOGRAPH data
• Graphic representation and post-processing features
• Data analysis
• Manual or automatic tree ring detection

Measurement and analysis (professional version)

• DECOM™ continuously records the RESISTOGRAPH® profiles during measurement.
• You can store additional information in the data header.
• Decay and other wood abnormalities can be specifically highlighted in the profile.
• Pictures can be integrated for a better object documentation.
• The document can be printed.

Tracing the rings tree ring detection (scientific version)

• Tree ring limits are automatically or manually marked by DECOM™.
• You can calculate the width of the tree rings as well as intra-annual density variables and store them in a format compatible with TSAP-Win™.

Mathematical functions for advanced users (scientific version)

• Using mathematical routines (e.g. trend adjustment, indexing etc.), the profiles can be analysed even more precisely.
• Statistical data can be stored in tables and used by other programs.
