Chlorophyll a Sensor

Hydrolab provides the most accurate Chlorophyll a sensor available on a multiprobe.


Ultra-compact size designed by specifically for integration into the Hydrolab DS5X, DS5, and MS5
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


Provides the most accurate measurement of Chlorophyll a because of electronic filtration of ambient light, efficient optical coupling, and quality optical components
Incredibly fast response time through electronic filtration of ambient light
Excellent turbidity rejection due to small sample volume design and high quality optical filters
Cost optimized for affordability and value
