The intuitive color touch screen operation of this spectrophotometer can directly display the operation prompts of the hash program on the screen. Combined with intuitive range bar chart display, automatic recognition and error alarm of colorimetric dishes, as well as the newly added AQA function and other humanized designs, can bring you a brand new user experience, reducing the additional work of reconfirmation and giving customers more confidence in test results.

Features and advantages:

The DR3900 desktop spectrophotometer is equipped with applications for over 220 testing methods, which can be widely used for water quality monitoring in industrial, municipal, environmental, educational and other fields. The usage characteristics of its spectrophotometer are:
● Quasi dual beam spectrophotometer
● Direct reading - Read concentration values directly
800 × 480 pixel 7 'color touchscreen style full Chinese operation menu, clearer and more intuitive
● Built in application with over 220 water quality testing methods, and can also create up to 100 user-defined programs
● Automatically recognize pre made hash reagents labeled with barcodes
For important parameters such as COD, automatically measure 10 values at different locations, remove outliers, and then take the average,
And the final average result can be displayed within 5 seconds
The new AQA function makes the use of the spectrophotometer simpler. AQA steps can now be easily defined, planned, executed, and archived.
Added reminder function, so that operators will not forget the standard measurements performed regularly. AQA menu in system check
Contains programs for checking and analyzing quality. The configuration is also completed here, for example, the usage of each spectrophotometer is validated using standard solutions,
And conduct interference testing using mixed solutions.
● Optional LINK2SC software allows data from the SC1000 digital controller to coexist with laboratory data
DR3900 displays the ability to quickly identify and analyze irregular data; Immediately achieve real-time calibration of online probes as needed after comparison;
As a result, bidirectional transmission of laboratory and online data is achieved, eliminating the need for on-site calibration of probes.
● It can display the usage steps of the spectrophotometer on the screen, reducing the probability of incorrect operation and eliminating the need to print the operation process
The software for using the spectrophotometer can be updated in real-time at any time through USB or a straight in cable
● Equipped with data storage function, capable of storing 2000 sets of data and 100 user-defined programs
The spectrophotometer has a USB interface before and after use for easy application updates and experimental data downloads using a USB flash drive
The network interface facilitates the network transmission of data
● Can directly connect to a printer and print experimental results
The use of the spectrophotometer has password protection and timer functions.
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, experimenter and other information. Data can be directly downloaded or transferred to a computer through USB interface and Ethernet cable, facilitating data storage and management.
