Optical spectrometric analyzers
Optical spectrometric analyzers use UV-VIS spectroscopy technology to measure water and liquid quality parameters continuously and in real time – without chemical reagents. By directing a beam of light through a sample and analyzing the absorbed spectrum, these instruments provide accurate measurements of key quality indicators directly in the process or in the field. They are widely used in industrial wastewater monitoring, municipal treatment plants, natural water bodies and process water applications.
Typical challenges in water quality monitoring
- Traditional laboratory analysis is time-consuming and delays real-time process control
- Chemical reagent methods cause recurring costs, waste disposal, and calibration complexity
Fluctuating wastewater loads require rapid response rather than periodic single samples - Remote installation points make wired infrastructure and manual sampling impractical
- Regulatory requirements require audit-ready permanent data logs
How optical spectrometric analysis works
A broadband UV-VIS light source emits radiation through a measuring cell containing a water sample. The detector records the transmitted spectrum and compares it with calibrated reference spectra. Multivariate algorithms extract simultaneous measurements of multiple parameters from a single optical scan – COD, BOD, TOC, nitrate, turbidity, color and spectral absorption coefficient (SAC). Since no reagents or consumables are required, these analyzers provide continuous, low-maintenance operation, ideal for demanding industrial conditions.
Main areas of application
- Municipal and industrial wastewater treatment – monitoring of inflow and outflow flows
- Surface water and river quality monitoring
- Drinking water production – detection of organic pollution
- Industrial process water control in chemical, food and beverage and pharmaceutical plants
- Combined Sewer Overflow (CSO) Monitoring
- Mining and leachate applications
MetriNet® multiparameter water quality monitoring system
Allows simultaneous, continuous monitoring of several key water quality parameters in real time. The modular system combines different sensors into a single platform and ensures reliable measurements without complex maintenance.
The system is widely used for monitoring drinking water, wastewater, surface water, industrial processes, and water distribution networks, where continuous quality monitoring and rapid response to changes are required.
SiteBox – portable water quality monitoring station
Allows for quick installation of a temporary or mobile monitoring point. The system integrates multiple analyzers and communication tools, so measurement data can be transmitted remotely in real time.
The solution is perfect for emergency situations, short-term projects, water network diagnostics, field research, and temporary water quality monitoring.
