DR900 multi-parameter portable colorimeter
The DR900 multi-parameter portable colorimeter adopts IP67 protection grade dustproof and waterproof, and has excellent seismic performance, which is convenient for you to use in harsh outdoor conditions. In addition, DR900 has built-in 90 measurement programs, which can meet the measurement of multi-parameters such as COD, TOC, ammonia nitrogen, etc .; can set the collection menu, convenient and quick access to commonly used measurement programs; provides multi-mode reading function, is an ideal portable multi-parameter water quality testing instrument.
- working principle:
Spectrophotometry is a method that uses a substance to selectively absorb light of a certain wavelength to identify a substance or determine its content.
The multi-parameter water quality tester is suitable for municipal sewage, tap water, drinking water, boiler water, cooling water, water treatment, environmental monitoring, industrial process monitoring and water quality testing in education, agriculture and other industries.
-Instrument features and advantages:
● Provide a variety of reading modes, including concentration,% light transmittance, and absorbance, to meet different reading needs of users.
● 90 measurement programs are preset, in addition, users can also build 10 measurement programs according to their needs.
● The favorite menu can be set to facilitate quick selection of commonly used measurement programs.
● With blank adjustment and standard adjustment functions, it can correct the differences between different batches of reagents.
● The data storage capacity is up to 500, including the summary test results, date, sample ID, etc., complying with the GLP standard, using the USB interface for data transmission, which not only ensures the traceability of the data, but also facilitates the output.
● The screen has a backlight display function, which is convenient for users to operate the instrument in a dark place or direct sunlight.
● Optional Chinese operation interface, simple and intuitive instruction icons can guide users to complete the program or menu settings, the interface is more friendly and easy to use.
● It conforms to ergonomic design, is easy to operate, adopts IP67 protection grade, has excellent anti-drop and anti-seismic performance, and is particularly suitable for field measurement and emergency occasion measurement.
