Chlorophyll a+b in Environmental Monitoring

Chlorophyll a+b in Environmental Monitoring

Monitoring chlorophyll a+b together provides a complete and accurate understanding of the environmental monitoring of algae in water bodies. Chlorophyll a is present in all photosynthetic algae, while chlorophyll b is commonly found in green algae and higher plants. Measuring their combined fluorescence strengthens water quality assessments and supports early detection of ecological changes.

AlpHa’s XC-CHLAB sensor utilizes patent pending optical technology with the following unique features:

  • Industry leading minimum detection limit at 0.02 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
