Product Applications

1. Fouling resistance and stable data

The four-electrode graphite structure minimizes the effects of polarization and fouling, making it suitable for high-salinity and highly polluted waters.

2. Low maintenance costs

Combines automatic cleaning with a protective design to reduce the need for manual maintenance and frequent cleaning.

3. Multi-parameter capability; one unit replaces many

Simultaneously measures EC, TDS, salinity, temperature, reducing the number of devices and overall system costs.

4. Comprehensive IoT solution

Offers an integrated setup comprising sensors, wireless modules, buoys, automatic cleaning systems, cloud platforms, and alarm systems.
