CDOM in Research & Education
Measuring Colored Dissolved Organic Matter (CDOM) is crucial for understanding the dynamics of organic carbon and water quality. In university research & education labs, CDOM sensors help students and researchers explore key topics in aquatic ecosystems and biogeochemical cycles.
AlpHa’s XC-CDOM sensor utilizes patent-pending optical technology with the following unique features:
- Industry-leading minimum detection limit at 0.01 ppb
- Automatic temperature compensation
- Analog (0 – 3 V) or digital (RS-485 MODBUS RTU) output formats
- Options for custom OEM sonde multiparameter and stand-alone configurations
