The resolution of the sensor itself is infinite. The resolution of read-
ings is determined by connected data logger, e.g.
CR1000: 1.5 µm
Dendrometer logger DL18: 0.2 µm
Dendrometer dependent:
Max. ± 4.5% of reading (stable offset)
Dependent on the connected data logger, e.g.:
CR1000:±(0.04% of reading+4.4µm)
Dendrometer logger DL18: ±0.1%
<0.2 µm in the whole range
<1%
Outdoor condition: -25 to 70C air temperature, 0 to 100% relative
air humidity
