Induskey INK299 CDOM Sensor Comprehensive

1. Product Overview
The INK299 is a high-sensitivity, self-cleaning CDOM sensor designed for continuous online monitoring of colored dissolved organic matter in aqueous environments. Built on ultraviolet fluorescence technology, it delivers stable, accurate measurements for rivers, lakes, and high-salinity scenarios like seawater. Its integrated mechanical cleaning brush eliminates bubbles, reduces contamination interference, and extends maintenance intervals, ensuring long-term operational reliability. With a compact 316L stainless steel housing, RS485 MODBUS communication, and pre-calibrated parameters, it enables easy on-site deployment, simplified secondary recalibration, and low-maintenance operation across industrial and environmental water monitoring systems.

 2. Sensing Technology & Self-Cleaning System
Sensing Technology
Adopts the 'ultraviolet fluorescence method'—the gold standard for CDOM detection. The sensor emits specific-wavelength UV light to excite CDOM molecules, which then emit fluorescence at a longer wavelength. The optical system detects and quantifies this fluorescence, with intensity directly proportional to CDOM concentration. Calibrated against quinine sulfate solution, it ensures high accuracy and linearity for both natural and industrial water matrices.

 Self-Cleaning System
Features an 'integrated mechanical cleaning brush' that addresses the core pain point of optical sensors: biofouling and contamination. The brush actively removes microbial adhesion, eliminates air bubbles, and minimizes fouling-induced measurement drift. This mechanism extends maintenance intervals, reduces manual upkeep, and ensures exceptional measurement stability during long-term submerged monitoring—critical for remote or hard-to-access water bodies.
