DZS-707 Multi parameter Water Quality AnalyzerDetailed product description：

Characteristics of DZS-707 Multi parameter Water Quality Analysis Instrument:

1. Can simultaneously test the temperature, pH (electrode potential), conductivity meter (TDS, salinity), and dissolved oxygen (oxygen saturation) of a sample
2. Using a computer virtual operation structure, the modular electronic unit converter only converts the signals from each sensor and transmits them to the computer for processing. Computer software undertakes all the operation and analysis functions of the instrument, with a small size and low cost.  
3. The instrument operation software developed on the Windows system platform has data processing functions, which can manually or automatically record measurement data and display the recorded data in the form of curves and tables. The data can be saved in Access database format, and can also be converted to Word document formats or Excel spreadsheets.  
4. The software supports system connection and connects to the system server through a network interface to transmit analysis and testing information such as sample number, testing personnel, testing data, testing date, and testing time to the system server for comprehensive processing of testing data.  
5. The converter of the instrument can be connected to a computer through the RS-232 interface or through a network interface, allowing the computer to remotely operate the instrument through the network.  
6. The software supports system connection and connects to the system server through a network interface to transmit analysis and testing information such as sample number, testing personnel, testing data, testing date, and testing time to the system server for comprehensive processing of testing data.
