  • Excellent turbidity rejection due to small sample volume design and high quality optical filters
  • Available with solid Secondary Standards to provide a quick and simple method to verify the sensor’s stability over time
  • The secondary standard can be adjusted to correlate to a known chlorophyll concentration
  • Three auto-selected gain ranges provide a wide measurement range of 0.03 to 500 µg/l for chlorophyll a
