This device can be used to measure water quality in general households, and compatible sensors are used to measure water level. This value can reflect the cleanliness of the water and can be used for water quality testing in the field of domestic water and hydroponics. Generally, tap water is within 100, and purified water is within 10.

This device is plug and play and easy to use. The wide voltage supply of 3.3~5.5V and the analog signal output of 0~2.3V make this product compatible with 5V, 3.3V control system, which can be easily used in the ready-made control system. The excitation source used for measurement uses an AC signal, which can effectively prevent probe polarization, extend probe life, and increase the stability of the output signal. The TDS probe is a waterproof probe that can be immersed in water for long periods of time.

NOTE:

• TDS probes cannot be used in water above 55 °C.
• The TDS probe should not be placed too close to the edge of the container, as it will affect the display.
• The head and lead of the TDS probe are waterproof and can be immersed in water, but the connection interface and the signal adapter board are not waterproof. Please pay attention to use.
