Introduction of Jaymaster's Tree Clinic Equipment

Jaymaster Tree Clinicl uses PiCUS sonic tomography sound waves to investigate the internal conditions of trees.

A series of nails are placed around the tree in the measurement plane where we have identified the weaknesses that require further testing of the visual inspection and this is the measurement point and is used to send or receive sound waves.
The distance between measurement points is carefully measured and recorded by the field technician.
A sound wave is created by a hammer tapping one of its fingernails.
The PiCUS equipment measures the flight time of the sound waves between the transmitting point and the other receiver.
The software draws a "speed" or "density" map of the tree by calculating the apparent sound velocity (distance / time) and combining the measured tree structure with the acoustic data recorded during the assessment.
The speed of sound is related to the density of the tree and therefore to the density of the tree.
With the electronic hammer, we can record a full resolution tomographic image of fewer resolutions with 6 to 8 sonic sensors.

  • PiCUS Tomography

    PiCUS Tomography

    • PiCUS tomography can measure even the most complex trees and root flares quickly and accurately.
    • PiCUS Calliper, with Bluetooth connectivity and automatic integration with expert software, is the fastest and most reliable tool for recording tree structures.
    PiCUS Treetronic3

    PiCUS Treetronic3

    • PiCUS Tretronic3 is integrated into the portable cases of Picus3 and Tritronic3.
    • The modular design of the caliper allows you to store all your parts in a sturdy carrying case.
    • The PiCUS Calliper3 can be easily assembled in the field with two working sizes of 1630 or 2150 mm.
    Sonic data recording

    Sonic data recording

    • A standard way to measure acoustic data is to connect one sensor to each measurement point.
    • The flight times of the sound waves generated by tapping each nail are recorded on each of the other sensors and used to calculate the tomography.
    • This shows how to sketch.
    CAS Micro Weighing

    CAS Micro Weighing

    • Model name : MW-2
    • We use electronic scales with a precision of 1/2000 ~ 1/3000.
    • There are various weighing units
      (Gram, Miligram, Carat, %, Pcs)
    • RS232C Interface Basics / LCD Display
  • Konica Minolta SPAD 502 Plus Chlorophyll Meter

    Konica Minolta SPAD 502 Plus Chlorophyll Meter

    • The SPAD 502 Plus Chlorophyll Meter measures plant chlorophyll content or "green content" instantly to limit harvesting or risk of excessive hyper fluorosis.
    • SPAD 502 PLUS quantifies subtle changes or trends in plant health long before it is visible to the naked eye.
    • Noninvasive measurement Fix the meter on a leafy tissue and get index chlorophyll content within 2 seconds.
    • We evaluate nitrogen requirements by comparing the SPAD levels in the field with university guidelines or appropriately modified reference script.
    • The study shows a strong correlation between SPAD measurements and leaf N content.

Powerful software compares all recorded velocities at one measurement level and shows where the sound waves travel slower than in the "fastest" region. There are three main color groups to be careful in analyzing tomographic images.

· Brown color (light brown to dark brown), green color, violet-blue-white color.
· brown shade indicates dark wood and green area indicates early rot.
· Purple is a decayed tree, and a blue color indicates hard cracks, cracks, and that wood are too small to transmit sound waves.

Images collected with tomograms can be used to identify critical areas for further testing.
The purple-blue-during-gamut area can only be displayed in purple color.
The example above shows a tomographic image of standard, violet (no blue), and gray color.

* These color definitions are part of the PiCUS expert software.
