SJG-705 online multi parameter water quality monitoring instrumentDetailed product description：

Characteristics of SJG-705 online multi parameter water quality monitoring instrument:

The instrument can simultaneously measure temperature pH、ORP、 Testing of conductivity or TDS, dissolved oxygen concentration, and saturation.
The instrument adopts a modular structure, and each measurement parameter uses an independent online real-time measurement board. Except for the temperature measurement board, other parameters can be combined arbitrarily.
There are three options for digital communication: RS-232, RS-485, and Ethernet
Optional automatic cleaning function can be used to clean the electrodes and flow cell by adding cleaning agent and rinsing.
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.
The instrument operation software has a curve chart copying function, which copies the curve chart to the clipboard for other software to paste and use.
Computers can remotely operate instruments through RS-232, RS-485 digital lines or network interfaces.
