Dendrometer Circumferential MIJ-02 Rotary Type3
What is dendrometer ?
Dendrometer is sensor that help researcher, growers, and forester to measure the growth of plants. Dendrometers are mostly used by researchers to measure the growth of a stem, trunk, branch, roots or fruits for long term observation.
Very ancient type of measurement is by using tape or band which wrapped around the trunk of a tree. This kind of measurement takes time and it will not give us exact result and also researches need to go to the place over the time, and record the plant growth daily, weekly or monthly.
To get exact result of plant growth, we need to avoid ancient type of measuring.
Can you see μm changes on your eyes?
Combined with a data logger, our dendrometers enable both diurnal and seasonal changes in hypertrophic growth, that is, automatic reading over a long period of time at short intervals. In addition, stable measurement in μm units, which is not possible with the visual type, but our dendrometer is possible to see in μm units.
Dendrometer Type 3 is an evolution of Type 2 that is easier to use and non-destructive.
Some users may be using a combination of Type II and MIJ-12 waterproof logger, but Type 3 has the same cable connector as Type 2, so the logger can be used as it is.
・Selectable nondestructive or screw mount (Need to purchase nondestructive KIT for nondestructive method)
・Wire typed dendrometer allow measurement immediately after set to measurement object.
・Potentiometer and pulley can be rotate 30 degree
・Set the wire position close to the measurement object (5mm) that allow to obtain absolute value
・Wide measurement Range (30mm)
・Ratiometric output lead to avoid potentiometer thermal characteristics
・Wide range of measurement Object (Measurement Object above Φ40mm～inifinity)
