Product Description

Soil Irrometer tensiometer is made up of pressure gauge, acrylic tube and ceramic probe, after the acrylic tube filled with water, ceramic probe gets wet and it can prevent outside air into the ceramic probe. When there is pressure difference between measured soil water potential and tensiometer, the water in tensiometer will infiltrate into the measured soil until the balance reached. So at that moment, the value shown on the pressure gauge is the measured soil water potential.

Application range.

Soil water suction is an indicator of the strength of the soil water potential and is closely related to the flow of soil water and its effectiveness on plants, and differs from the meaning of soil water content in that it reflects the dryness of the soil in terms of the strength of the soil water potential, not in terms of how much it is.Generally speaking, the greater the soil suction, the smaller the water content; the less the soil suction, the more the water content.The product can be widely used in irrigation system control, water level monitoring, leakage monitoring, agricultural science research, environmental monitoring, forest fire prevention and other scenarios.

Convenient Measurement.

Simple structure, easy to measure, continuous observation with fixed points and positioning.

High Accuracy.

PC tube body, high quality microporous ceramic.

Highly sensitive linear number, value changes, environmentally friendly materials that do not damage the soil of open crops.

Attention.

When transporting or using the sensor, please take it gently to avoid damage to the device caused by severe shocks. The clay head should not be oiled, as this may block the micro-pores and cause the apparatus to malfunction.

Model	Length	Testing range	Attention
TEN-30	30 cm	0~100 Kpa	Length can be made as customized. (Standard length is the length of transparent polycarbonate tube in the middle of tension meter tube)

TEN-120	120 cm

Principle and operation.

When the soil become dry, contact with the ceramic head of soil potential tend to be sucked out tube of water surface tension. And form a partial vacuum on the top of the tube. After the irrigation or rainfall, water is sucked back into the tube reduce vacuum.

High vacuum value represents dry soil. If low vacuum value, represent wet soil. In general, should place several monitoring points.Each monitoring point must have 2-3 sets of tension meter with different length. Then you can know each monitoring point of moisture content in different depth and moisture during irrigation period.

The tension meter system could be used for many years, reliable need only a small amount of maintenance. Instrument do not require calibration and zero.

Read and record data regularly in the field when using. For example, draw soil moisture motion graph 2-3 times in a week, learn different crops water requirements from department of agriculture. It can help irrigator to estimate water requirements in next irrigation interval and related preparation before irrigation.
