Portable Turbidity Meter LMPTM-501 quickly determines the number of suspended particles in water. Microprocessor-based circuitry assures high precise and repeatable readings. It uses an infrared light source and 90° scattering method, which is compliant with the ISO 7027 method. Portable design allows you to take measurement on-site instead of bringing solution back to the laboratory. 200 sets of data are stored and can be transferred to PC by USB communication interface. Single measurement mode automatically recognizes the stable readings.
