Soil Moisture Sensor

Figure 30 Soil Moisture Sensor ML2x

Soil Moisture Sensor ML2x features a new technique with the accuracy

of ±2 % soil moisture. The ML2x sensors offer high accuracy and

extended lifetime in permanent or temporary measurements of 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.
