Accurately measure and monitor tree growth rates using the DEN1 Dendrometer Meter, a wireless, stand-alone logging instrument that can support up to 5 DBV60 sensors.
For complete monitoring solutions, the DEN1 can used in combination with the SFM1 Sap Flow Meter, PSY1 Stem Psychrometer, LSM1 Light Sensor Meter or the ICT International automatic weather station.
