Description

The TN500 uses a tungsten filament lamp as the light source and 90° scattering method, which is compliant with the U.S EPA 180.1 method for the determination of turbidity in drinking, ground, surface, and saline waters, domestic and industrial wastes. The instrument is designed for water quality professionals, offering long-term reliability in high-accuracy turbidity measurement with an intuitive operation system, simple calibration, and GLP data management.
