Hash DR3900 desktop visible light spectrophotometer

The DR3900 desktop spectrophotometer is equipped with applications for over 240 testing methods and more than 100 user-defined programs. (For measurable parameters, please refer to Table 7 on page 17 of the sample.)
The "Hash Spectrophotometer and Colorimeter Measurement Parameter List" can be widely used for water quality monitoring in industrial, municipal, environmental protection, education and other fields. Its characteristics are:

• Quasi dual beam spectrophotometer
• 800 × 480 pixel 7 'color touchscreen style, fully Chinese operation menu, more clear and intuitive
• For important parameters such as COD, automatically measure 10 values at different locations, remove outliers, and then take the average. The final average result can be displayed 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 makes data processing more timely and effective, storing, calling, and analyzing data within a specified time period
• The new AQA feature makes QA simpler: AQA steps can now be easily defined, planned, executed, and archived. Added reminder function, so that operators can

We will not forget the standard measurements that are regularly performed. The AQA menu in the system check contains programs for checking and analyzing quality. The configuration is also completed here, for example, each method
Validation with standard solution and interference testing with mixed solution

• Optional LINK2SC software allows data from the SC1000 digital controller and laboratory data to be displayed simultaneously in DR3900, enabling rapid identification of irregularities, data analysis, and real-time calibration of online probes as needed. This enables bidirectional transmission of laboratory and online data, eliminating the need for on-site calibration of probes
• The instrument has USB interfaces in both the front and back for easy application program updates and experimental data downloads using a USB flash drive, and can also be transmitted using a straight in Ethernet cable. The instrument can be directly connected to a printer and print experimental results
• Equipped with password protection and timer function
• Multi user management allows administrators and standard users to set different permissions

The DR3900 desktop spectrophotometer has data storage function and can store 2000 sets of experimental data, including date, time, test results, sample name, and experiment
Employee information. Data can be directly downloaded or transferred to a computer through USB interface, Ethernet cable, for easy storage and management of data
