Industrial Grade Online Potassium Ion Sensor (RS485/Modbus)

This RS485 water quality potassium ion sensor is designed specifically for online water quality monitoring, integrating high-precision ion detection, digital communication, and industrial grade protection. It can be widely used in surface water, aquaculture water bodies, industrial drainage, and sewage treatment scenarios. The product is centered around stability and reliability, helping users to real-time monitor changes in potassium ion concentration and improve water quality management efficiency. Its core advantages are specifically reflected in the following aspects:

1. Accurate measurement and intelligent compensation
Using a highly selective potassium ion electrode, the response is fast and the repeatability is good. Built in automatic temperature compensation function can effectively eliminate the influence of water temperature changes on measurement results, ensuring accurate and consistent data in different seasons and different water areas.
2. Digital output, convenient integration
Standard RS485 interface, supporting standard Modbus RTU protocol, can be directly connected to data acquisition instruments, PLCs or cloud platforms to achieve remote monitoring and multi device networking. Simultaneously available 4-20mA analog output, compatible with various control systems.
3. Durable and sturdy, with strong environmental adaptability
The whole machine has reached IP68 protection level and can work in immersion for a long time; The shell is made of corrosion-resistant materials and equipped with 3/4NPT threads or immersion installation methods to adapt to harsh working conditions such as humidity, pollution, and even short-term flooding.
4. Low power consumption and easy maintenance
Wide voltage power supply (12-24V DC), with a typical power consumption of only 0.2W, suitable for outdoor sites powered by solar energy or batteries. Support two-point on-site calibration, simple operation, and low maintenance cost.
