The SN-3001-LDO-N01-20 dissolved oxygen sensor utilizes a fluorescence quenching method, where an oxygen-sensitive luminescent layer is excited by an internal LED. The presence of oxygen molecules reduces the fluorescence lifetime, which is precisely measured to calculate the dissolved oxygen concentration. This optical principle eliminates the need for membranes, electrolytes, or oxygen consumption, resulting in minimal maintenance and excellent long-term stability.
Housed in a robust, IP68-rated enclosure, the sensor is designed for continuous submersion and operation in temperatures from 0 to 50°C. Its RS485 Modbus RTU output provides a standardized digital signal for seamless connection to industrial control systems, data acquisition units, or environmental monitoring networks. The sensor’s rapid response time and accuracy make it ideal for dynamic water quality assessment.
