AquaSense-Chl
Modulated fluorescence chlorophyll-a sensor with coherent detection, self-cleaning option, and RS485 / Modbus output for algal biomass and water-quality monitoring.
AquaSense-Chl uses modulated excitation and coherent detection to deliver sensitive, drift-resistant chlorophyll-a fluorescence measurements. The reagent-free optical method enables unattended, low-impact monitoring, and the optional self-cleaning brush keeps the optical window free of biofilm for long-term deployments.
Modulated Fluorescence
Modulated excitation and coherent detection lift sensitivity and rejection.
Reagent-Free
Optical method without chemicals or consumables.
Self-Cleaning Option
Wiper accessory prevents long-term biofouling on the optical window.
Continuous Monitoring
Stable readings for long-duration in-situ deployments.
Modulated Fluorescence
Modulated excitation and coherent detection lift sensitivity and rejection.
No Reagents
Reagent-free measurement keeps the unit clean and environmentally friendly.
Self-Cleaning Wiper
Built-in cleaning device protects long-term stability against biofouling.
RS485 + Modbus
Digital RS485 output with Modbus RTU for logger and PLC integration.
Continuous Monitoring
Designed for unattended in-situ deployments on buoys and stations.
Stable & Sensitive
Optimised optics deliver low detection limits with low drift.
Overview
AquaSense-Chl is an optical chlorophyll-a fluorometer that uses modulated excitation and coherent detection to lift sensitivity and reject ambient light. The reagent-free optical method avoids consumables and chemical waste, and the optional self-cleaning brush keeps the optical window free of biofilm for long-term deployments — even in highly productive water.
The probe outputs RS485 with the Modbus RTU protocol, making it a drop-in fit for AquaSense-Multi multi-parameter sondes and OceanBuoy / OceanBed observation systems. It is widely used for algal-biomass tracking, harmful-algal-bloom monitoring, and ecological water-quality research.
