Dendrometers
Equitensiometers
Sap Flow Sensors and
Data Loggers as
representative agent
for Japan.
To study relationships between environment
and plants, there is need for precise,
simultaneous data on plant responses and
environmental variables that influence
these responses.
Ecomatik Dendrometers are highly precise
instruments for continuous monitoring of
radial and vertical changes of plant
tissues e.g. stems, fruits,leaves etc.
DR
Radius Dendrometer
DR
DR for Abies veitichii (SHIRABISO)
Radius dendrometer curve of a spruce tree
For measuring changes in radius.
Suitable for diameters>8 cm.
The stem is injured by two screws.
Sensor of DD/DR Dendrometer
DD Diameter
Dendrometer
DD for trunk
DD for branch
For measuring changes in diameter.
Suitable for diameter<20 cm
(>20 cm on request).
No injury to plant.
The frame can be reduced to meet
any size of plant.
■Specifications of Sensor DD/DR/DF
Measurement Range: 11 mm without reset
continuously extendableby resetting
the frames/ wire cables.
Accuracy: < 5 μm (measuring with two channels)
with u logger < 7μm
Resolution: depending on data logger used,
i.e. using 12 bits logger<5 μm,
use u logger <7μm
Linearity: ± 0.5 %
Output signal: 0-50,000 ohm
Power supply: No power supply required
Temperature Coefficient:
2 single-ended channels measurement < 0.1 μm/c
1 single-ended channel measurement＜0.04％/Ｃ
Environment: Out door condition: - 30 to 40℃
air temperature. 0 to 100 % relative air humidity
Weight of sensor: 13 g without cable and frame
Cable length: 2 m standard, expandable up to 100 m
Collection of data: continuously with data logger
DC Circumference
Dendrometer
DC
For measuring changes in circumference
of stem and fruit.
Suitable for diameter>2 cm,
no injury to plant.
Very light,
a complete sensor without cable
is only 16 g.
DC2 Circumference
Dendrometer 2 New!
DC2
Features:
Wide measuring range: 60 mm in circumference,
continuously extensible by resetting the wire
cable. Suitable for any tree size from 2 cm in
diameter.Enhanced sensitivity due to automatic
adjustment of tensile force of the wire cable
to tree size.No injury to plant

DF Fruit and Vegetable
Dendrometer
DF Apple
Apple Growth Curve by DF
DF Grape
DF Cucumber
For measuring changes in diameter of fruits,
vegetables and cereals.
Suitable for diameter<11 cm (>11 cm on request),
The anti-move system ensures the centered
position of the object, no injury, the frame
can be reduced to meet any small size of plants.
DV Vertical
Dendrometer
DV Vertical Dendrometer
For measuring vertical variation of one
section of plant stem. The data reflect
important parameters of plant physiology:
1) The variation of water content
in the plant body and xylem water
potential, respectively;
2) The variation of plant orientation
during growth.
If using three DV, the effects of water
potential and of plant orientation can
be separately detected.
Vertical: Vertical Changes of
Stem Length(μm/0.5m)
Horizontal: Time of Month
Black: South side
Red: North-Eastern Side
Green: North-Western Side
Blue: Mean of three Sides
Vertical changes of stem length
of a Quercus suber tree.(KORUKUGASHI)
The tree is equipped with three vertical
dendrometers at different sides
(South, North-Western and North-Western).
Due to competition pressure from South-Eastern
the tree tends to south-Westwern direction.

Dendrometer Data Logger-ulogger
The Ecomatik dendrometers do not require
any power supply and are maintenance-free.
They are applicable under remote conditions to
carry out measurements.
A combination dendrometers + ulogger enables you
to monitor plant growth with one small internal battery
for up to two years.
The uloggers has 4 channels.
Every channel can operate one dendrometer or
one thermister thermometer.
