Product Overview:

The HACH DR3900 visible light spectrophotometer features a quasi-dual-beam optical system, automatically calibrates wavelengths, and comes with over 200 preset user programs, covering almost all conventional water quality parameters. The color touchscreen features a Chinese operating interface, automatically analyzes, detects, and stores 2,000 sets of experimental data, making it a highly accurate visible light spectrophotometer.

Working Principle:

The DR3900 visible light spectrophotometer uses spectrophotometry to conduct qualitative and quantitative analysis of the substance based on its selective absorption of light of a certain wavelength.

Instrument Features:

● Equipped with an excellent quasi-dual-beam optical system capable of automatic wavelength calibration, ensuring accuracy in routine water quality parameter monitoring, reducing manual calibration errors, and core performance meeting professional visible light spectrophotometer standards.

● Built-in over 200 user programs, covering almost all conventional water quality measurement parameters.

● Capable of automatic analysis of detection data and filtering out important parameters in test results. For example, when COD automatically measures 10 values at different positions, the system program first removes outliers, then averages the values, displaying the final average in about 5 seconds.

● Optional LINK2SC software enables two-way transmission of laboratory and online data, eliminating the need for on-site probe calibration, reducing on-site operating costs, and improving the timeliness and accuracy of data transmission.

● Supports storage of 2000 sets of experimental data, can connect to networks and printers for data transfer, facilitating quick export and printing of test data, preventing data loss, and meeting laboratory data management standards.

● Built-in AQA function: Easily define, plan, execute, and archive according to AQA steps; Added reminder function to prevent operators from forgetting to perform standard measurements regularly; The AQA menu also includes program options to check the quality of the analysis; The solution preparation is completed here.

● Uses an 800×480 pixel 7' color touchscreen, paired with a fully Chinese operation menu and an operation guide program. The screen displays operation steps to reduce the chance of incorrect operation. No need to print the operation process, making the detection results clearer and more intuitive.

● Equipped with trend and ratio analysis functions, allowing storage, retrieval, and analysis of data within specified time periods for more timely and effective data processing.

● Equipped with password protection and timer functions, allowing different permissions for administrators and standard users to enable multi-user management, ensuring equipment operation security while meeting the management needs of multiple collaborative laboratories.

Application Areas:

The DR3900 visible light spectrophotometer is widely used for water quality monitoring in industrial, municipal, environmental protection, education, and other fields.
