Application:Quickly and accurately measure soil water potential in the wild or field.

Principle:water saturationAfter inserting the ceramic head into the soil, the soil tension draws water from the ceramic head into the soil, and the reading on the tension meter at equilibrium is the soil water potential.

System composition:

Tensio 100fieldportableTension meter with acrylic glass tension meter head, polycarbonate protective film on the back, and precise vacuum gauge (diameter)63mm）Filling screws, pressure pre regulator that can shorten measurement time and discharge air, ceramic head（SKA 100 FF, 10x2）Brass bracketV2A vertical pipe (diameter 10 mm) and V2A tip.

There are three lengths to choose from.

System performance indicators:

origin: Germany

Usage steps:

1．Remove the tension meter and soil drill from the sleeve, check the water level in the tension meter, unscrew the nut on top and fill it with deionized water.

2．At the experimental site, first drill a hole with a soil drill, and then place a tension meter into the hole.

3．waitAfter 5-30 minutes of balancing, the values on the table can be read. If the water level drops too quickly, do not let it drop to the intersection. You can unscrew the nut and fill it with water, then wait for the balance reading.

Daily maintenance:

In general, no special maintenance is required. Pay attention to keeping the ceramic head of the tension meter moist, that is, keeping water in the tension meter at all times. If the clay head is too dry, it will crack and be damaged.
