CL200 ExStik® Waterproof Chlorine Meter. This revolutionary technique measures Direct Total Residual Chlorine from 0.01ppm to 10ppm. It makes non-subjective measurements unaffected by interferences associated with traditional colorimeters and spectrophotometers like sample color, turbidity, light, and pollutants.
TB400 Portable Turbidity Meter. Test the turbidity of municipal water, food and beverage water, and other aqueous solutions where fluid clarity is important. Portable design allows you to take measurement on-site instead of bringing solution back to the lab. Measures up to 1000 NTU (Nephelometric Turbidity Unit) with 0.01 NTU resolution.
