DR3900 Desktop Spectrophotometer, 320-1100nm, Hach (CAT#: STEM-S-0003-YJL)

DR3900 Desktop Spectrophotometer, 320-1100nm, model DR3900 is manufactured by Hach. The DR3900 visible spectrophotometer has a built-in quasi-double-beam optical system, automatic wavelength calibration, and more than 200 preset user programs, covering almost all conventional water quality parameters. The color touch screen is equipped with a Chinese operation interface, which can automatically analyze, detect and store 2000 sets of experimental data. It is a visible light spectrophotometer with accurate measurement. DR3900 Visible Spectrophotometer adopts spectrophotometric method, according to the characteristic that the measured substance has selective absorption of light of a certain wavelength, the qualitative and quantitative analysis of the substance is carried out.

Reduce errors - 10 readings are averaged within 5 seconds to avoid errors caused by contamination and scratches on the surface of the cuvette.
Color screen, easy to operate
Color full touch screen - direct reading of data concentration, intuitive range bar graph display.
Procedure guide - guide the operation process step by step, eliminating the need to consult the method manual.
A good helper for data processing
Data processing-trend and ratio analysis, making data processing easier and faster.
Network transmission function - convenient for data transmission, program update and method manual download.
Humanized design, reduce workload
The LINK2SC software of the whole module can realize the intelligent comparison between the laboratory data and the online data with one key, and realize the real-time calibration of the online probe immediately after the comparison, and there is no need to calibrate the probe on site.
Humanized design such as the newly added AQA function can bring you a brand-new experience and reduce the additional work of reconfirmation
