Frequently Asked Questions (FAQ)
Q
What measurement principle does the Chlorophyll Sensor use?
The Chlorophyll Sensor uses fluorescence-based detection combined with optical modulation and coherent signal processing technology. This method excites chlorophyll molecules in the water and measures the emitted fluorescence, providing accurate and interference-free readings even in dynamic or turbid water environments.
Q
What is the measurement range of the LMS-CHL100 Chlorophyll Sensor?
The LMS-CHL100 has a chlorophyll measurement range of 0–500 µg/L with an accuracy of ±3% F.S. It also measures water temperature in the range of 0–50°C with an accuracy of ±0.5°C, making it suitable for a wide variety of freshwater and marine monitoring scenarios.
Q
Does the sensor require chemical reagents for operation?
No. The Chlorophyll Sensor is completely reagent-free. It relies solely on optical fluorescence detection, which eliminates the need for any chemical reagents. This not only reduces ongoing operational costs but also minimizes environmental impact, aligning with sustainable water quality monitoring practices.
Q
How does the self-cleaning system work and why is it important?
The sensor is equipped with an integrated automatic wiper that periodically cleans the optical window to remove biofilm, algae, and sediment buildup. This self-cleaning mechanism ensures long-term measurement stability and accuracy, significantly reducing the frequency of manual maintenance — especially important for remote or continuously deployed monitoring installations.
Q
What communication protocol does the sensor support, and how can it be integrated into a monitoring system?
The Chlorophyll Sensor outputs data via RS-485 using the standard MODBUS protocol. This makes it highly compatible with a wide range of data loggers, PLCs, SCADA systems, and IoT water quality monitoring platforms. It operates on a 9–24VDC power supply (12VDC recommended), allowing flexible deployment in both fixed and portable setups.
Q
In what environments and applications can the Chlorophyll Sensor be deployed?
The sensor is designed for versatile deployment across multiple environments. Its 316L stainless steel housing ensures durability in corrosive and high-pressure underwater conditions. It is widely used in lakes, rivers, reservoirs, coastal marine zones, aquaculture facilities, drinking water treatment plants, and industrial wastewater systems — anywhere continuous and reliable chlorophyll monitoring is needed.
