Watermark soil moisture sensor - 22.4mm

14.27.05

The inexpensive and easy to install Watermark soil moisture sensor is a granular matrix soil moisture sensor to measure soil moisture tension between soil particles. This is relevant for plant growth and soil stability.

  • Proven stable calibration
  • Range of measurement from 0 to 239 cb (kPa)
  • Fully solid-state
  • Not affected by freezing temperatures
  • Internally compensated for commonly found salinity levels
  • Compatible with AC or DC reading devices

Description

Watermark sensors can be used as an economical and maintenance-free replacement for tensiometers in most agricultural and landscape irrigation environments. These sensors will not dissolve in the soil, are insensitive to salt and frost resistant.

They monitor the current situation in the soil. An alternating current is applied to a sensor that is sensitive to soil moisture tension. Due to the consistent pore distribution of each sensor, a reasonably accurate measurements will be gained, with a measuring range of 0 - 199 kPa (0 - 199 cbar). 

The soil temperature measured can be set in the soil moisture meter (14.27.01) allowing for temperature correction. The electrical resistance is converted by the soil moisture meter into moisture tension in kPa.

Applications

  • Irrigation research
  • Soil moisture measurements
  • Leak Detection
  • Agronomy Research
  • Environmental Monitoring
  • Water Table Monitoring
