ECOMATIK provides the DL18-BLE (Bluetooth Low Energy) dendrometric data logger that covers all relevant logging features and options for accurate and efficient dendrometric measurements.

Suitable for connecting 1 to 4 dendrometers, temperature compensated effects, 16 bits, resolution 0.2-0.5 µm (regardless of dendrometer type), RAM for data storage of 1,900,000 (sufficient for a one-year measurement with 4 dendrometers, 1 min measurement interval), USB port, an internal battery lasts more than 1 year of measurement.
Ideal for long-term measurements with dendrometers.
Supplied with weather box and protective visor.

ECOMATIK dendrometers are compatible with all popular data loggers (eg Campbell, Delta-T, DT80). We provide assistance in connecting our dendrometers with data loggers.
