Description

Mini-Systems with Data Logger DL 18 or DL 18 - BLE

Our Mini-Systems are based on the data loggers DL 18 (interface: USB to PC withWindows or MacOS) or DL 18-BLE (interface: Bluetooth Low Energy to Windows PC, orTablet / Smartphone with Android or iOS).

Both loggers feature 4 precise and high-resolution measuring channels (temperature-compensated, 16 bits) for connecting various analogue sensors, such as dendrometers, soil moisture sensors, temperature probes (T-soil,T-surface,T-Tissue), leaf temperature sensors (LAT-B3),and T/RH air sensor.

A possible sensor combinations would be for example: 1x dendrometer + 1x T/RH air sensor (this sensor type occupies 2 channels) + 1x soil moisture sensor (max. number of soil moisture sensors per DL 18 is 1 piece, due to the higher power consumption of this sensor type).

Our mini measuring system can operate independently due to their robustness (weather resistant protective box and metal roof are included); battery-operative, extremely low power consumption (2replaceableAAA batteries, lifetime> 1 year);as well as their large internal memory (1,900,000 data points). Mini-Systems are thus ideal for long-term measurements in outdoor conditions with a spatially decentralized distribution of the measuring points.
