Product Overview
The SX-CDRNA Series fluorescence-method 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 digital RS-485 output enables convenient system integration.
Main Features
- Digital sensor with RS-485 output, Modbus protocol
- No electrolyte required; high resistance to interference;
reduced recalibration requirements - Zero oxygen consumption; no flow-rate limitation
- Built-in temperature sensor with automatic temperature
compensation - Built-in calibration parameters, factory-calibrated for immediate installation and use
