DBV60 Voltage Band Dendrometer

Accurately measure and monitor tree growth rates

Whole tree water relations research has just become easier and more accurate. The DBV60 Voltage Band Dendrometer is similar to the DBL60 Logging Band Dendrometer however has a cable for the connection to a DEN1 Dendrometer Meter or other voltage logger. Standard cable lengths are 5m however can be extended as needed.

The DBV60 is the dendrometer of choice for telemetry systems and remote data logging platforms. Combined with the MCC2G, data measured by the DBV60 can be downloaded anywhere in the world where GSM is available.

DBV60 SE and Differential Barewire

The DBV60 Band Dendrometer is used to measure short and long term changes in stem circumference. The DBV60 measures stems with a diameter greater than 8cm. The DBV60 is a highly accurate dendrometer with a measurement resolution of 1µm (0.001 mm) stem circumference change. The DBV60 is IP-65 rated and is designed to measure stem changes over many years.
The DBV60 Band Dendrometer is a non-invasive measurement device attached to the stem with an inextensible stainless steel band.  The stainless steel band has a linear thermal co-efficient of 17.3 x 16 per °C. Therefore thermal variations caused by daily or seasonal changes in temperature have no measurable impact on the operation of the DBV60.
