Product Overview
The SX-CDRQA Series dissolved oxygen sensor is designed for aquaculture water-quality monitoring. It uses fluorescence-method measurement technology with high-performance fluorescent material. The sensor does not consume oxygen, has no flow-rate limitation, and requires no electrolyte solution. It requires minimal maintenance and calibration, offers high resistance to interference, and provides stable measurement performance. A built-in temperature sensor provides automatic temperature compensation,
and the digital RS-485 output supports convenient system integration.
