The newly upgraded online residual chlorine sensor by Shandong Tianhe Environmental Technology Co., Ltd. in 2025 is a precision device used for real-time monitoring of residual chlorine content in water bodies. Its core function is to convert residual chlorine concentration into measurable electrical or optical signals through electrochemical or optical principles, providing key data support for water disinfection effect evaluation and water quality safety management. At the meeting, many industry insiders and customer friends arrived at the scene. After understanding, everyone highly affirmed and fully recognized the product.

The technical director of Shandong Tianhe Environmental Technology Co., Ltd. stated that the online residual chlorine sensor for water quality has high detection accuracy and is suitable for low concentration residual chlorine (such as below 0.05mg/L in drinking water); Strong anti-interference ability, suitable for turbid, high chromaticity or complex water quality (such as sewage and wastewater). Monitor the residual chlorine concentration in fish hatching ponds, seawater tanks, and aquarium circulating water to prevent excessive residual chlorine from causing harm to aquatic organisms. ”
core functionality
Real time monitoring: Continuously collect residual chlorine data in water bodies, timely reflect changes in disinfection effectiveness, and avoid insufficient residual chlorine leading to microbial exceedance or excessive production of harmful by-products.
Automatic compensation: Some models integrate temperature compensation and pH compensation functions to eliminate the influence of environmental factors on measurement accuracy.
Data output and integration: Supports analog signals (such as 4-20mA, 0-5V) or digital signals (such as RS485, Modbus, I2C) output, making it easy to interface with PLC, SCADA systems, or IoT platforms. Support wireless transmission (such as LoRa, NB IoT) to achieve remote monitoring.
Alarm and linkage: It has upper and lower limit alarm function, and when exceeding the standard, it will interlock the valve and dosing equipment to stop or start, ensuring safety.
This press conference has been a complete success, and we welcome customers who have such needs to come.
