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.
