Root and aquatic plant dendrometer (DRO)

The DRO Dendrometers is designed for continuous measurement of roots, aquatic plants and creepers. The device is waterproof. The sensor rod is protected with soft, light resistant rubber. The metal clamp protects the sensor from excessive pressure from top soil. The unit has specific weight similar to water, when used under water therefore has no impact on plants. It is easy to install and maintenance free. By more than 1 year test, it has proven itself well.

Advantages

Waterproof, suitable for use in/on the soil and under  water

Low pressure at the measuring point

Ideal for long-term measurement with less manpower

Disadvantages

Only for diameter smaller than 2 cm

 

Delivery
