Installation Method

Note: Install the test at least 2 cm from the bottom and side walls of the container. The sensor should not be installed upside down or horizontally, but at least at an angle of 15 degrees or more. The interface of sidewall mounting must be beveled at 15 degrees, otherwise it will affect the normal testing and use of the electrodes.

Application

Tips: What makes this sensor environmentally friendly?

The water quality sensor uses non-invasive and chemical-free methods to measure conductivity and TDS, reducing the need for reagents or harmful chemicals. Its durable and long-lasting design minimizes waste, and the low power consumption (0.2W @12V) ensures energy-efficient operation. These features make it an eco-friendly choice for sustainable water quality monitoring.
