1Purpose:

The Soilspec tensiometer system is a soil water potential measuring instrument produced in Australia that is easy to operate, stable, reliable, and inexpensive.Equipped with a digital reading meter, it can directly display soil water potential values

IIPrinciple:

The Soilspec tensiometer system adopts a principle similar to that of plant roots absorbing water from the soil. When the water in the soil decreases and the water potential decreases, the water in the tensiometer tube buried in the soil will seep out from the porous ceramic head. At this time, a certain vacuum degree is formed in the tensiometer tube. By measuring the vacuum degree in the tensiometer tube, the change in water potential in the soil can be reflected.

IIIcharacteristic:

1．Easy to operate, stable and reliable

2．digital display

3．No need for specialized maintenance

4form:

Handheld reading meter:It can be divided into storage data type and read-only read table.

Tension meter tube:The standard length of the tension meter tube is optional:15. 20, 30, 45, 60, 75, and 90 cm,The standard length refers to the length of the white plastic sleeve in the middle of the tension meter tube.Tension gauge tubes with special length requirements can be customized.

enclosure:Insert pins and rubber plugs, etc.

5Technical parameters:

● Handheld reading meter

A handheld reading meter with only one reading key for easy operation. The measuring pins are placed on the back of the meter, and there is a white pin protective cover that can be removed when replacing the pins.

The handheld reading meter has the following characteristics:

◎ Automatic zeroing function: The system will automatically zero every time it is connected;

◎ Automatic power-off function: Approximately5 Automatically cut off the power after minutes, which will eliminate power consumption caused by the power being constantly turned on;

◎ Battery level display function: The battery indicator indicates the battery level, and when the battery needs to be replaced, it will emit a sound and display a warning;

◎ Use one9V alkaline battery, the battery can last for one month and can only be used with alkaline batteries;

Reading the meter allows for complete revision;

Regularly replace the measuring pins (once a month), which are very cheap. The pins will become dull after use, and if not replaced, it will damage the plug of the tension meter.

● Tension meter tube

SoilspecThe tension meter tube of the tension meter system is a plastic tube with a white plastic sleeve in the middle (used to protect the tension meter tube inserted into the soil and keep the temperature of the tension meter tube consistent with the soil temperature to ensure the accuracy of the measurement results), a porous ceramic head at the lower end, and an open plastic tube at the upper end.

There are several standard lengths for tension gauge tubes:

15、20、30、45、60、75 and90 cmTension gauge tubes with special length requirements can be customized. The standard length refers to the length of the white plastic sleeve in the middle of the tension meter tube.
