Watermark Soil Moisture Sensor - with PVC Tube
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.
- Easy to install
- Proven stable calibration
- Fully solid-state
- Not affected by freezing temperatures
- Internally compensated for commonly found salinity levels
- Compatible with AC or DC reading devices
The inexpensive and easy to install Watermark soil moisture sensor with pvc tube is a granular matrix soil moisture sensor, measure soil moisture tension between soil particles. This is relevant to plant growth and soil stability. Thanks to the pvc tube, it is easier to insert the sensor deeper into the ground.
The sensor monitors 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.
