OPM 100 Spectrophotometer
Reliable Analyser for Wastewater Quality Measurement
Download Brochure
The OPM 100 SERIES system is the ideal solution for accurately measuring Chemical Oxygen Demand (COD), Total Suspended Solids (TSS), and Biochemical Oxygen Demand (BODc) online. The advanced OPRUSS Spectrophotometers are compact yet precise instruments suitable for various water types. They utilize innovative Dual Beam Absorption technology, which analyzes light absorption in both ultraviolet and visible ranges to detect contaminants.
Benefits
● Zero reagent use
● Capability for outdoor installation
● Effective operation in different water types, making it suitable for treated wastewater applications, where conditions can change and interferences can be high.
