Chlorophyll a+b in Research & Education

Chlorophyll a+b in Research & Education

Understanding chlorophyll a+b concentrations is essential for evaluating the total photosynthetic pigment content in aquatic and terrestrial ecosystems. In university research & education labs, chlorophyll a+b sensors empower students and researchers to examine pigment dynamics, assess plant and algal health, and track environmental change over time.

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
