MT22A Sensor
Distributed by MMM Tech Support
Description
The MT22A sensor is a sensor that was developed based on the well-known Teros 12 sensor model.
The MT22A was specifically designed for use in all common growing media. This sensor measures the water content from 0-100%, the substrate /soil 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 its high accuracy and unbeatable low price.
