Models of Turbidity Meter

Labtron Turbidity Meter provide measurement of cloudiness or haziness of fluid caused by presence of suspended particles. They consist of light source including laser, for measuring turbidity levels accurately. Their photodetector captures scattered light, converting it into measurable electrical signals for analysis. They feature sample chamber where water samples are placed for turbidity testing. Our Turbidity Meter evaluates water clarity in wastewater treatment, aquaculture, storm water management, recreational water testing.
