(ii) CarboVis® 705 IQ TS (BOD, COD,TSS) Optical BOD and TSS probe (60 mm) with spectral processing wastewater treatment plants with integrated ultrasonic cleaning. Supplied with multifunctional slide and Shock-Absorption-Rings BOD/COD/TOC/ TSS Sensor for higher range. Spectral Online Sensors The CarboVis sensor measure the total spectrum range from ultraviolet to long wave visible light (200-720 nm; UV-VIS sensors) or in the ultraviolet range (200-390 nm; UV sensors). The measured values are determined from the high information content of the spectral data.
