TSS Meter

TSS sensors measure suspended solids concentration by detecting the interaction between infrared light and suspended particles in water. The sensor emits infrared light into the sample, where suspended particles absorb and scatter part of the light. An optical receiver detects the intensity of the scattered light, which changes with particle concentration. The electronics analyze this response and convert it into a TSS or sludge concentration value. 

Supmea sensors use infrared absorption and scattered-light technology based on the ISO 7027 method, helping reduce the influence of sample color. Some models also use optimized optical paths, real-time compensation and optional self-cleaning brushes to support stable online measurement. Regular cleaning and calibration help maintain accuracy.
