Accurate growth measurements made easy
The D1 Dendrometer is a simple tool that enables you to manually
measure changes in the circumference of tree stems over time. It's
designed to be installed, left in place, and periodically visited
to record changes in the circumference resulting from tree or stem
growth. Designed for serious field research and forest management,
it gives you a durable, low-maintenance way to monitor changes in
trunk circumference over time-offering insight into growth
patterns, stress response, and carbon storage.
The D1 was engineered with painstaking attention to detail by
our team in Munich, Germany with features built for real-world
reliability:
Low-friction Astralon tape
with minimal thermal expansion for consistent measurements, even
in extreme weather. Friction is reduced by manufacturing the
eyelets without burrs and eliminating printing on the bark-side
surface of the tape. It wraps around the trunk of a tree and
fastens with a spring mechanism that allows the tape to expand as
the tree grows. Researchers can measure the change in diameter,
typically at longer intervals (once a year).
A uniquely engineered Vernier scale
that makes readings precise and easy to interpret-no guessing,
no recalculations.
Pre-converted diameter readings
for quicker field notes and less confusion later. The
measurement scale is in units of ?, so there is no need to convert
circumference to diameter.
The D1 measures trees with diameters from 10 to 66 cm. Two tapes
can be connected to measure larger trunks. Stems less than 40 cm in
diameter should use the short spring, and the longer spring should
be used on stems greater than 40 cm in diameter.
Built to last
Designed to stay in place and perform for years in woodland and
forest environments.
Whether you're documenting tree growth, studying ecosystem
change, or supporting long-term carbon modeling, the D1 gives you
clarity you can rely on-without the need for batteries,
connectivity, or fragile tech.
