Combi Dendrometer | Ecomatik

The ECOMATIK Combi Dendrometer is a growth dendrometer designed for continuous monitoring of plant dimensional variations, from very young shoots to large-diameter trees. It uses one sensor combined with two interchangeable mounting systems, enabling measurements on both small and large plants with the same sensor.

Two configurations are available—DD-S2/DR7 and DD-S3/DR6—with measurement ranges adapted to different plant sizes.

Advantages

• One sensor for two applications: small and large plants
• Continuous, long-term growth monitoring
• Very high resolution (dependent on the data acquisition system)
• High stability and low thermal drift
• SDI-12 compatibility and analog output
