Hash DR3900 desktop multi parameter water quality analyzer

characteristic:

-Instrument features and advantages:
800 × 480 pixel 7 'color touch screen with a fully Chinese operation menu, providing clearer and more intuitive detection results
DR3900 has the advantage of automatic analysis of detection data, screening important parameters in the detection results, such as COD automatically measuring 10 values at different positions. The DR3900 system program will first remove outliers, then take the average, and display the final average result within 5 seconds
The operation guide program displays the operation steps on the screen, reducing the probability of incorrect operations and eliminating the need to print the operation process
The trend and ratio analysis function enables effective storage of data and facilitates the retrieval of analysis data within a specific time period
