Blue Green Algae in Environmental Monitoring

Blue Green Algae (Phycocyanin) in Environmental Monitoring

The detection of phycocyanin is a critical component of environmental monitoring of blue-green algae (cyanobacteria). AlpHa’s XC-BGAF sensor utilizes patent-pending optical technology with the following unique features:

  • Minimum detection limit at 2 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
