Main features

• The tensimeter is reliable and durable, with a strong structure, suitable for field use.
• Uv resistant, durable material.
• The interface is tightly sealed and the protection level reaches IP68.
• The sensor does not need to be removed from the soil during water addition or emptying process.
• The measurement process responds quickly.
• Infield 7 was used, or Campbell's was used.

Measuring principle

    Soil water can enter and exit the sensor through the ceramic cup, resulting in the change of water quantity in the water storage pipe, resulting in the change of pressure at the top of the water storage pipe. The pressure sensor located at the top of the water storage pipe can simulate the change of pressure, so as to obtain the corresponding water potential.
