The Teros 12 Sensor is the successor of the GS-3 & 5TE models. This sensor has been specially designed for use in all common growing media. This model measures the water content from 0-100%, the substrate, the temperature between -40 and +50°C and the electrical conductivity (EC) in the range 0 to 23 dS/m.
