Overview

The 229 is a sensor that measures soil water potential from -10 to -2500 kPa. It requires that you connect it to either the CE4 or CE8 current excitation module. A Campbell Scientific data logger controls the current excitation module, measures the sensor, and calculates soil water matric potential.

Benefits and Features

• Compatible with most Campbell Scientific data loggers
• Measures a wide range of matric potential
• Measurements not affected by salts in the soil
• Long lasting, with no maintenance required
• Compatible with AM16/32-series multiplexers, allowing measurement of multiple sensors
