• UV 254 spectral absorption without any reagents or consumables. • Multi-parameter measurement: SAC254, CODeq, TOCeq & BODeq, Turbidity eq • Modbus RS-485 digital communication. • Automatic Turbidity compensation. Applications • Urban wastewater treatment: detecting organic load variations during input / treatment process / output. • Treatment of industrial effluents • Surface water monitoring • Fish farming, aquaculture (freshwater) • Drinking water: monitoring Organic matter in raw water, oxidation process, coagulation, activated carbon filtration. The Spectral Absorption Coefficient (SAC) at 254 nm helps determine the Organic Content of a water sample but also the COD, TOC and BOD parameters by applying the appropriate correlation coefficients Technical Characteristics Measurements Measurement principle UV 254 nm absorption Compensation Turbidity at 530 nm Wave lengths Internal temperature Type of detector 254 nm (turbidity correction at 530 nm) Light sources Silicon Photodiode Optical paths LED UV 254 +/- 5nm and 530 +/- 5 nm Measurement frequency 2 and 50 mm Ingress Protection rating IP68 Max. immersion depth 50 meters Operating temperature 0-40°C Storage temperature -10°C to +50°C PH range pH2 to.pH12 Dimensions (D x L) (mm) 48x371 or 48x419 (see overall dimensions diagram) Weight 1600 - 1800g depending on the optical path (cable not included) Equipment Body: Stainless steel 316 (1.4401) • Optical windows: Quartz (Corning 7980) • Cable: Bare wire with polyurethane sheath • Seals: Fluoroelastomer (FPM/FKM)
