Suitable for developing irrigation and fertigation strategies of trees and plants, band dendrometers are high resolution dendrometers, capable of measuring changes of 0.001 mm. All DB-60 series band dendrometers have a minimum measurement of 80mm, and an upper limit defined by the length of band tape (15m). Each dendrometer can measure 64mm before requiring adjustment.
The DB-60 series has a measurement resolution of 0.001 mm, and the DBL60 can store up to 50,000 readings (approximately 4 years at hourly intervals) whilst the DBS60 and DBV60 use external loggers with either internal storage (DEN1 or SDI-12 Logger) or IoT connection for cloud visualisation and storage (SNiP-DBS).
- DBL60 Logging Band Dendrometer: Self-contained logger with Infra-Red connection for downloading data.
- DBV60 Voltage Band Dendrometer: Voltage signal output.
- DBS60 SDI-12 Band Dendrometer: SDI-12 output.
