Bench top Turbidity Meter (with built-in printer) LTM-C13

Bench top Turbidity Meter (with built-in printer) LTM-C13

Bench top turbidity meter (with built-in printer) LTM-C13 comes with microprocessor controlled system, works on 90° scattered light principle to measure water turbidity in nephelometric turbidity unit i.e. NTU. The formazine standard solution of turbidity mentioned in ISO 7027 is used for turbidity analysis. This turbidity meter delivers highly accurate results with better numerical calculations to meet GLP standards.
