Product Overview
The SX-CDRCA Series self-cleaning dissolved oxygen sensor uses fluorescence-lifetime measurement technology with high-performance fluorescent material. It does not consume oxygen, has no flow-rate limitation, and requires no electrolyte solution. The sensor requires minimal maintenance and calibration, is resistant to hydrogen sulfide interference, and provides high accuracy and stability. A built-in temperature sensor provides automatic temperature compensation. The integrated self-cleaning brush helps prevent microbial fouling, extends maintenance intervals, and improves operational reliability
