Hash/HACH Visible Spectrophotometer from the United States

Related introduction:
The DR3900 desktop spectrophotometer is an intelligent desktop spectrophotometer product launched by Hash Company in 2011. 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. If combined with the full module LINK2SC software, intelligent comparison between laboratory data and online data can be achieved with just one click. After comparison, real-time calibration of online probes can be achieved immediately as needed, without the need for on-site calibration of probes.
This spectrophotometer has an intuitive color touch screen operation interface and 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.
This instrument is on the market that covers both regulatory requirements and is well connected to online instruments. It can be widely used for water quality monitoring in industrial, municipal, environmental protection, education and other fields.

Hash/HACH Visible Spectrophotometer from the United States

Features and advantages:
◆ Quasi dual beam spectrophotometer
◆ Direct reading type - directly reading concentration values
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. The final average result can be displayed within 5 seconds
The new AQA function makes QA 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. The AQA menu in the system check contains programs for checking and analyzing quality. The configuration is also completed here, such as verifying each method with a standard solution and conducting interference testing with a mixed solution.
◆ Optional LINK2SC software allows data from the SC1000 digital controller and laboratory data to be displayed simultaneously in DR3900, enabling 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.
◆ The operation steps can be displayed on the screen, reducing the probability of incorrect operations and eliminating the need to print the operation process
The instrument software can be updated in real-time at any time through USB or direct insertion of Ethernet cables
◆ With data storage function, it can store 2000 sets of data and 100 user-defined programs
The instrument has USB ports both before and after, making it easy to update application programs and download experimental data using a USB flash drive
The network interface facilitates the network transmission of data
◆ Can directly connect to a printer and print experimental results
◆ It has password protection function and timer function.
Multi user management allows administrators and standard users to set different permissions
