OPM 300 Spectrophotometer
Reliable Analyser for Wastewater Quality Measurement
Download Brochure
The OPM 300 SERIES system is designed for online measurement of Chemical Oxygen Demand (COD), Total Suspended Solids (TSS), and Biochemical Oxygen Demand (BODc). The OPRUSS Spectrophotometer is a compact yet accurate device suitable for various water types. Utilising advanced technology, it scans ultraviolet and visible light to detect contaminants.
Key Benefits:
● No reagents required.
● Suitable for outdoor use.
● Handles treated wastewater with variable conditions and high interference.
● Provides precise measurements for effluent and sewage treatment plant water.
