MEC10 Sensor
Distributed by MMM Tech Support
Description
The MEC10 sensor is a sensor for measuring volumetric water content, EC value and soil/substrate temperature with digital signal.
The MEC10 sensor is suitable for standard measurements in substrates and soils, and is distinguished not only by its good accuracy but also by its unbeatable low price, which makes it possible to implement a large number of measuring points at low cost. This sensor measures the water content from 0-100%, the soil/substrate temperature between -40 and +80°C, and the electrical conductivity (EC) in the range of 0 to 23 dS /m.
This sensor is characterized by good accuracy and an unbeatable low price.
