◆ Timed-Read function (timed measurement mode): There are two timed reading modes, including timed stop measurement and timed automatic interval measurement.
◆ Cont-Read function (continuous measurement mode): Through this function, you can understand the process of continuous change of measurement.
3. Intelligent operating system, navigation menu operation, good user experience
◆ User management: It can support 8 user login passwords to realize the management of user ID and password.
◆ Safety management: self-diagnosis and power-off protection function.
◆ Electrode management: electrode ID management (5 electrodes for each type, 20 sets of data for each electrode), recording electrode calibration history, and reminding electrode life.
◆ Calibration management: automatically buffered solution, PX measurement module supports 6-point calibration; Calibration edits are supported, such as deleting, adding calibration points, and calibration speed.
◆ Interface Management:DZS-708L multi-parameter Water Quality AnalyzerYou can create shortcuts, and there are multiple ways to enter the start measurement interface; The display is 7-inch color and supports backlight setting adjustment, which can be used in laboratories with different conditions.
4. Powerful data management function, in line with GLP specifications, traceable and complete information
◆ Data inquiry: The storage data can be checked according to the storage number, storage time, operator ID, method name, measurement sample ID, electrode ID, etc., and the results of the query can be displayed in the form of curves.
◆ Data statistics: support statistics, analysis and comparison of measurement data.
◆ Data storage: Massive storage, the storage capacity of measurement results of each measurement module is not less than 1000 sets.
◆ Data Output:DZS-708L multi-parameter Water Quality AnalyzerThere are RS-232 and USB interfaces, which can support U flash memory; Users can compile printout requirements, and there are three output methods: GLP format, standard format, and user-defined format.
◆ Data input: Able to read U disk to store measurement data.
5. It can be measured in batches and can be connected to an autosampler
◆ It can be connected to SCH-01 autosampler, which can realize automatic measurement of multiple samples and automatic calibration of PH electrode
◆ Real-time display of test methods, measurement curves, measurement results, dynamic display of measurement curves
◆ Support for viewing, creating, copying, editing, and deleting measurement methods
◆ Key input mode:Characters and numbers
