EMS Band Dendrometer DRS26 for Large Trees from 30 cm

Precisely Monitors Radial Tree Growth With Fast Detup for Research and Forestry Applications

The EMS DRS26 band dendrometer is a digital sensor that accurately measures the circumferential increment of large tree trunks with micrometer precision, without affecting their natural growth. Its non-invasive design and high resolution make it ideal for studies of plant growth, water stress, and environmental response.

Features

• Precise digital measurement with sub-micrometer resolution.
• Non-invasive installation that does not affect tree growth.
• No upper limit on trunk diameter.
• SDI-12 digital output for easy integration with monitoring systems.
• Low maintenance and energy requirements.
• 64 mm measurement range for circumferential growth.
• Provides data on growth, water stress, and trunk freezing.
• Compatibility with different tree diameters by changing the base plate.

Non-Invasive Tape Fixing System

The EMS DRS26 dendrometer uses a tape fixing system (D RL 26 C) that does not damage the tree or affect its natural growth. This innovative method:

No effect on tree growth Integrated value for the entire radial profile at the measured height Almost identical thermal expansion of wood and stainless steel

Complex Dendrometric Data

Dendrometer data Efficient tool for field measurement Includes information on growth, water stress, and trunk freezing Low maintenance and energy requirements compared to sophisticated systems like sap flow Together with soil water potential measurement, it provides a realistic picture of water stress and tree response

SDI-12 Data Output Asynchronous serial communications protocol for intelligent microprocessor-based sensors. The sensor typically takes a measurement, performs calculations based on the raw sensor reading, and outputs the measured data in engineering units. It allows the connection of a set of sensors in series on a cable line. For more information, visit the SDI-12 website. Measure trees with different diameters by simply changing the base plate.
