Digital UV-VIS Spectrometer for Comprehensive Water Analysis
The Endress+Hauser Memosens Wave CAS80E is a digital optical spectrometer designed for continuous monitoring of water and wastewater quality.
Traditional laboratory analysis often requires sampling, transportation and delayed results. The CAS80E performs measurements directly in the process, providing real-time information about water conditions and helping operators optimize treatment processes.
The compact spectrometer combines multiple measurement functions into one device, reducing the need for multiple individual sensors and simplifying measuring point design.
Typical applications include:
Drinking water monitoring
Municipal wastewater treatment
Industrial wastewater treatment
Surface water monitoring
Utility water management
UV-VIS Absorbance Measurement Principle
The CAS80E uses UV/VIS absorbance measurement technology from 200 to 800 nm.
The sensor analyzes how the liquid absorbs different wavelengths of light and uses application-specific models to calculate various water quality parameters.
This measurement principle enables:
Fast response to water quality changes
Continuous online monitoring
Multi-parameter analysis with one sensor
Reduced dependence on laboratory testing
The measured parameters depend on the selected application and calibration model.
Multiple Water Quality Parameters in One Sensor
