Overview

CDT-16B is made to measure soil water potential. This potential shows how much energy water has in the soil. It depends on factors such as gravitational potential, matric potential, and osmotic potential. The sensor works using different physical principles.

For example, some sensors look at the link between water content and the soil’s electrical conductivity or dielectric constant. As the water content changes, the electrical properties change as well. The sensor can turn these changes into signals to measure soil water potential.

Key Features

• Precise measuring range from -100kPa to 0kPa

• Equipped with RS485 digital and 4-20mA analog signals

• High Accuracy & Good Linearity

• IP67 fully waterproof and dustproof grade

• Easy Installation & Low Maintenance
