The EC Sensor is a next-generation soil analysis tool designed to simplify and enhance agricultural decision-making. Unlike traditional probes, this sensor is capable of measuring three critical soil parameters simultaneously—moisture, temperature, and electrical conductivity (EC). By combining these functions in a single, compact unit, it enables farmers, researchers, and agronomists to obtain highly reliable data in real time.
With its rugged IP68 design and long service life, the EC Sensor is built to withstand harsh environments, making it equally suitable for field farms, greenhouses, saline soils, and scientific research applications.
How the EC Sensor Works
The sensor uses advanced digital sensing technology and a compensation algorithm to ensure precise readings:
- Moisture Measurement – Detects volumetric water content in the soil to guide efficient irrigation.
- Temperature Tracking – Measures soil temperature to assess root health and crop growth conditions.
- Conductivity (EC) Monitoring – Evaluates dissolved salt and nutrient concentration, offering insight into soil fertility and salinity levels.
Its internal compensation system ensures that each parameter is calculated independently. This means that soil salinity does not distort the moisture reading, and temperature changes do not affect EC values—delivering unbiased and accurate data every time.
Key Features
- 3-in-1 Measurement – Combines moisture, temperature, and conductivity in a single probe.
- Rapid Response – Produces results in less than a second, stabilizing within two seconds.
- Durable Construction – Encapsulated with epoxy resin and fitted with stainless steel electrodes to prevent corrosion and electrolysis.
