The EC & TDS Sensor measures the conductivity, salinity, and total dissolved solids (TDS) in a liquid. The output signal can be RS485 or Analog Voltage. Determining the conductivity, salinity, and TDS of a liquid has many important applications. The EC & TDS Sensor is widely used in monitoring water quality.
The EC & TDS Sensor was designed with industry standards. And this EC & TDS Sensor (version B) comes with a waterproof aviation connector. It is designed with ATC (automatic temperature compensation), making sure the data is accurate regardless of the temperature changes. This EC & TDS Sensor is IP65 rated, waterproof in a tight seal, capable of withstanding long-term constant use in professional application scenarios. It comes with a cover that is rated IP68.
This EC & TDS Sensor has a MODBUS-RTU RS485 serial communications protocol or 0-2V output. It can be easily connected to and integrated with other devices such as data-loggers, controllers, and displays, etc. This cost-effective EC & TDS Sensor features low-power consumption, compact size, portability, and high integration, making it widely applicable in both indoor and outdoor environments.
Applications
