Description

This EC & TDS Sensor with hook-up wires measures the Conductivity, Salinity, and total dissolved solids (TDS) in a liquid and is widely used in monitoring water quality.

The EC & TDS Sensor is designed with industry standards. It is designed with ATC (automatic temperature compensation), which ensures the data is accurate regardless of the temperature changes. Its electrode is IP68, the transmitter is IP65 rated, waterproof in a tight seal, and capable of withstanding long-term constant use in professional scenarios. This EC & TDS Sensor comes with a MODBUS-RTU RS485 serial communications protocol and 0~2V Analog Voltage output. It can be easily connected and integrated with other devices such as data loggers, Converter, and displays. This cost-effective EC & TDS Sensor features low-power consumption, compact size, portability, and high integration.

Applications

Agriculture, Hydroponics, Aquaponics, Sewage treatment, Research, Environmental monitoring and Other environmental monitoring scenarios.
