Soil Water Potential Measurement​ introduction
The HLY-SH100 soil water potential measurement is used for field positioning detection and observation of soil water potential, which can further obtain soil water conservancy properties parameters such as soil moisture and hydraulic conductivity. This instrument utilizes the principle of a tensiometer and combines the method of one or more probes to improve traditional techniques. It is also possible to purchase only one set of instruments with multiple probes. The probe can be buried for a long time at different depths underground and on different measured plots, so that if you want to know the water potential at a certain point, you can connect the instrument to the probe and read the value.
Explanation of the values measured by HLY-SH100:
1. The measurement force value is within the range of 0-10Kpa: indicating humidity, which is too high for most crops.
2. The measurement force value is within the range of 10-30Kpa: indicating humidity, suitable for the growth of most crops.
3. The measurement force value is within the range of 30-50Kpa: indicating that dry and wet crops require watering.
4. Measurement force value within the range of>50Kpa: indicates dryness, and most crops require irrigation.

Soil Water Potential Measurement​ Function Introduction
