The SRWQ100-YL-105 residual chlorine sensor represents a significant advancement over basic dissolved oxygen or pH sensors. Unlike generic water quality sensors that only measure temperature or conductivity, this sensor specifically targets free chlorine—the key indicator of proper water disinfection.
