Overview:
The DJ-5020 Trunk Rain Collector is composed of an interception acquisition component, a rain flow sensor and a data logger. The start time, end time, duration and rate of tree trunk closure can be observed through the software, and the recorded data can be exported to Excel file and text format through the software, which is convenient for data analysis and processing. It is used for continuous automatic monitoring and recording of tree stem interception under the canopy.
Benefits and Features:
The Trunk water tube uses flexible materials, which can meet the collection work of trunk interception volume of different tree species and different climate environments.
Easy installation, smart outlook, easy to maintenance.
Small area, suitable for different environments.
High accuracy, support customized 5ml/time accuracy.
The data logger is powered by batteries and does not need an external power supply; the collection interval is 10 minutes, and the power can be continuously recorded for about 365 days.
It can simultaneously record the temperature data when tree trunk closure occurs.
