Chlorophyll a in Environmental Monitoring
Chlorophyll a in Environmental Monitoring
Monitoring chlorophyll a levels in water bodies is critical for assessing water quality and environmental health. Chlorophyll a sensors play a crucial role in detecting the presence and concentration of algae, which in turn have a direct impact on aquatic environments.
AlpHa’s XC-CHLA 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
