Applications
Widely used in water quality testing in industrial, municipal, environmental protection, education and other fields.
The DR3900 visible spectrophotometer has an excellent quasi dual beam optical system and can perform automatic wavelength calibration, with good performance and accurate measurement.
The DR3900 visible spectrophotometer has over 200 built-in user programs, covering almost all conventional water quality measurement parameters.
The DR3900 visible spectrophotometer can automatically analyze detection data and screen important parameters in the detection results. If COD automatically measures 10 values at different locations, the system program will first remove outliers, then take the average, and display the final average result within about 5 seconds.
The DR3900 visible spectrophotometer can be equipped with LINK2SC software to achieve bidirectional transmission of laboratory and online data, without the need to calibrate the probe on site.
The DR3900 visible spectrophotometer can store 2000 sets of experimental data and can be connected to networks and printers for data transmission.
Built in AQA function: easy to define, plan, execute, and archive based on AQA steps; Add reminder function, so that operators will not forget the standard measurements that are regularly performed; The AQA menu also includes program options for checking and analyzing quality; The solution configuration is completed here.
The DR3900 visible spectrophotometer adopts an 800 × 480 pixel 7 'color touch screen, paired with a fully Chinese operation menu and an operation guide program. The screen displays the operation steps, reducing the probability of erroneous operations. There is no need to print the operation process, making the detection results clearer and more intuitive.
The DR3900 visible spectrophotometer has trend and ratio analysis functions, which can store, call, and analyze data within a certain time period, making data processing more timely and effective.
It has password protection and timer function, and can set different permissions for administrators and standard users for multi-user management.
