Portable Turbidity meter LTM-A10 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.

Labtron pocket testers are small and compact in size, gives fast and accurate results. The Pocket testers consist of pH, ORP, TDS, dissolved oxygen, salinity and conductivity tester for various laboratory as well as outdoor applications. Measurements can be taken by inserting the probe in to the test solution and after gentle stirring, stable readings can be noted down.
