Industrial Conductivity, Salinity and TDS Sensor MODBUS-RTU RS485

ECTDS10 measures Conductivity, Salinity, TDS with temperature compensation. The output signal can be RS485, Analog Voltage. The sensor is applicable for industrial, water processing, sewerage system, irrigation, and smart agriculture, etc.

Features

• High performance: high accuracy, fast response, good repeatability
• Universal protocol: MODBUS RS485, 0-2V
• Wide-range power supply: 3.9V ~ 30V
• Robustness: suitable to be immersed in water for a long time
• Durable: anti-corrosion, automatic temperature compensation
• User-friendly: Easy to install and integrate

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.

ThisEC & TDS Sensorhas 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-effectiveEC & TDS Sensorfeatures low-power consumption, compact size, portability, and high integration, making it widely applicable in both indoor and outdoor environments.
