Portable Turbidity Meter LTM-A15


Portable Turbidity meter LTM-A15 with microprocessor controlled system, utilizes 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. Portable meter, used in field and lab scale analysis, delivers highly accurate results as per the GLP standards.
