optek turbidity meters and colorimeters

optek inline turbidity meters, lab turbidimeters and optical density probes can be specified to measure turbidity, haze, clarity and optical density in units of FTU, NTU, EBC, OD, PPM, percent and many others. Common process applications include filter performance and filter break monitoring; gas bubble detection; particle content and concentration; total suspended solids (TSS); interface detection; BOD; and leak detection. Specialised applications using probe sensors include fermentation, cell culture, cell density, biomass, dissolution and crystallisation.

optek colorimeters, VIS-NIR concentration analysers and colour monitors are suitable for many real-time measurements for improved process control. Installed directly in process pipelines, tanks and vessels using flow-through and probe type sensors, these analysers can be configured to measure the concentration of numerous chemicals and can be correlated to many colour scales including APHA, ASTM, Saybolt, ASBC-SRM, ICUMSA, AOCS and HAZEN. Typical applications include the concentration of bromine, chlorine dioxide, chlorine, nickel, copper, chromium, haemoglobin and chlorophyll, as well as colour addition and removal control, leak detection/carryover, product interface and dosing/blending control.
