Note
This Industrial EC & TDS Sensor comes in two versions. The main difference is in the cable connector. Please choose the version that best suits your needs:
(1) Version B: with a waterproof aviation connector. This version saves you time in deployment as you won't have to use screws to connect the cable to the data logger. And it can be used with SenseCAP Sensor Hub 4G Data Logger instantly with ease.
(2) Version A: with hook-up wires.
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.
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.
