In addition to having all the functions of 2100N, the 2100AN laboratory turbidity meter has expanded its turbidity measurement range and added chromaticity measurement function. Suitable for turbidity measurement in different fields such as drinking water, wastewater, surface water, groundwater detection, education, scientific research, industrial process control, and product quality control. The programmable signal averaging function, automatic calibration function, and built-in printer printing function of the instrument greatly optimize the testing process and facilitate data management; The ratio measurement mode developed using Hash Company's patented technology effectively ensures the elimination of chromatic interference; The sensitive fault self diagnosis function can promptly remind users to discover and eliminate instrument faults; The sample testing chamber can be purged with air to prevent light scattering caused by water vapor condensation, making it suitable for measuring turbidity of cold and hot water samples.The instrument has data storage function, which can be accessed throughHachLink ^TM The software willThe experimental data is directly downloaded to the computer for easy storage and management of the data. The built-in printer can directly printMeasurement results and related parameters.
