             SJG-705 Online multi-parameters water

                     quality meter for industry use


Product Description



It is applied in water quality analysis in the field of environmental protection, agriculture, education, scientific research and integrated service.


Main features:


1.It can simultaneously measure temperature, pH, ORP, conductivity, TDS and dissolved oxygen concentration and saturation.

2.It adopts modular structure and each measuring parameter uses independent measuring plate. The measuring plate is indispensable and other parameter measuring can be combined at will.

3.There are three digital communication ports which can be chosen: RS-232, RS-485, and ETHERNET.

4.The user can select automatic cleaning function. In this way, the electrode and flow cell can be cleaned by being washed with detergent.

5.The operation software provides data processing function on the base of Windows system. The measuring data can be recorded automatically or manually, and also the data can be displayed through curve and form. The data can be stored by Access data system, Word and Excel program.

6.The operation software provides curve copy function. The curve can be copied to clipboard and used by other software.

7.The instrument can be remote controlled by computer through RS-232and RS-485 digital port and network port.

8.The software can transmit the information such as sampling Number, testing person, testing data, testing date and testing time to system server for comprehensive processing.
