Low power consumption
RBRcoda chl-a: chlorophyll-a sensor
The RBRcoda chl-a is a real-time chlorophyll-a sensor rated for depths up to 6000 meters. Its compact design, fast sampling rates, low power consumption, and a high depth rating, make it suitable for use in a wide variety of applications.
- Low power consumption
- Depths up to 6000m
- MCBH-6-MP on all units
- RS-232 output
- Compact and lightweight
RBRcoda chl-a integrated into an RBRmaestro³ C.T.D
Robust and durable design
Easily integrates directly into your AUV or via the RBRlegato CTD
Sapphire windows facilitate automated wiping
Features & Configurations
The RBRcoda chl-a ensures high sensitivity to low concentrations across the measurable range (0-500µg/L). All optical components of the RBRcoda chl-a are robust and durable, selected to minimise aging due to UV/sunlight exposure, and thus show no minimal change in properties over extended deployments. Its sapphire windows facilitate automated cleaning by a wiper to keep them free of biofouling during long-term moored deployments.
