HACH DR3900 desktop spectrophotometer

HACH DR3900The desktop spectrophotometer is from Hash Company2011The newly launched intelligent desktop spectrophotometer product in the year. It is a new generation of network intelligent instrument that can be easily embedded in the company's intranet to achieve data transmission, and can also directly update software and user manuals online. This spectrophotometer is easy to use, if combined with the full moduleLINK2SCThe software allows for intelligent comparison between laboratory data and online data with just one click, enabling real-time calibration of online probes as needed without the need for on-site calibration.

DR3900The desktop spectrophotometer uses an intuitive color touch screen operation interface, and the operator can directly display the operation prompts of the hash program on the screen. Combined with intuitive range bar chart display, automatic identification and error alarm of colorimetric dishes, as well as newly addedAQAFunctional and personalized design can bring you a brand new user experience, reducing the additional work of reconfirmation and giving customers more confidence in the test results.

DR3900Desktop spectrophotometer with built-in 220 Application with multiple testing methods, equipped with data storage function, capable of storing2000 Group experimental data, including date, time, test results, sample name, experimenter, and other information. Data can be obtained throughUSBInterface, Ethernet cable, can be directly downloaded or transmitted to the computer for easy storage and management of data.

DR3900Desktop spectrophotometers can be widely used for water quality monitoring in industrial, municipal, environmental protection, education and other fields.

Performance characteristics:

l Quasi dual beam spectrophotometer

l 800×480Pixel based7”Colorful touchscreen style full Chinese operation menu, clearer and more intuitive

l built-in220Applications for multiple water quality testing methods can also be created up to100A user-defined program

l Automatically recognize pre made hash reagents labeled with barcodes

l For important parameters such asCODAutomatically measure different positions10Take a numerical value, remove outliers, and then take the average5 The final average result can be displayed within seconds

l all-newAQAThe function makes the use of the spectrophotometer simpler.AQAThe steps can now be easily defined, planned, executed, and archived. Added reminder function, so that operators will not forget the standard measurements performed regularly. In the system inspectionAQAThe menu contains programs for checking and analyzing quality. The configuration is also completed here, such as verifying the usage of each spectrophotometer with standard solutions and conducting interference tests with mixed solutions.

l OptionalLINK2SCSoftware that enables fromSC1000The data in the digital controller and the data in the laboratory are simultaneously presentDR3900To achieve rapid identification and analysis of 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.

l The usage steps of the spectrophotometer can be displayed on the screen, reducing the probability of incorrect operation and eliminating the need to print the operation process

l The software for using the spectrophotometer can be accessed at any timeUSBOr plug in the Ethernet cable to achieve real-time updates
