Fruit dendrometer DF2
For measuring diameter changes of small/medium sized, fast-
growing fruits
0-11 cm (>11 cm on request)
25.4 mm
The resolution of the sensor itself is infinite. The resolution of read-
ings is determined by connected data logger, e.g.
CR1000: 3.3 µm
Dendrometer logger DL18: 0.5 µm
Dendrometer dependent:
Max. ±1.97% of reading (stable offset)
Dependent on the connected data logger, e.g.:
CR1000:±(0.04% of reading+10µm)
Dendrometer logger DL18: ±0.1%
<0.2 µm / °C in the whole range
<0.7%
Outdoor condition: -25 to 70C air temperature,
0 to 100% relative air humidity
26 g without cable
Stabilized Vex of 0.5 – 10 VDC, power consumption practically zero
Stainless steel and Aluminum
5 m, extendable up to 100 m
