Soil Moisture Sensor

0105-026

Figure 31 ML2x Soil Moisture Sensor

ML2x Soil Moisture Sensor features a new technique with the

accuracy of ± 2 % soil moisture.

Traditional low cost sensors made of gypsum block dissolve even in a

short period of time when exposed to high moisture. The ML2x

sensors are very durable. The rods are 60 mm long, made of resilient,

solid stainless steel, and can be unscrewed and replaced if necessary.

All exposed materials are either stainless steel or durable plastic, and

the probes are fully sealed. This way they can also safely be buried

into the ground.

The ML2x probes offer high accuracy and extended lifetime in

permanent or temporary measurements of soil moisture.
