The RK500-29 Residual Chlorine Sensor stands as a paragon of precision engineering in water quality monitoring, engineered to meet the rigorous demands of industrial, municipal, and environmental applications where accurate residual chlorine detection is critical. Designed with cutting-edge capabilities, this sensor redefines reliability through its advanced Constant Voltage Method principle, delivering precise measurements across a versatile range of 02ppm, 05ppm (typical), and 010ppm, ensuring compliance with even the most stringent regulatory standards.
Built for durability and adaptability, the RK500-29 operates seamlessly in challenging environments, with a robust IP68 protection class safeguarding against dust and submersion, and a wide 050°C working temperature range that ensures performance in diverse climates. Its high-resolution 0.01ppm readout and ±5%FS accuracy empower users to trust critical data for process control and compliance monitoring, while low power consumption (<0.5W) and flexible power options (730VDC) make it ideal for both portable and permanent installations.
