EDO industrial dissolved oxygen sensor
Description of EDO industrial dissolved oxygen sensor :
EDO electrochemical dissolved oxygen instrument, specially designed for wastewater treatment process, function complete, easy to operate. High performance composite electrode is particularly suited to the bad working condition of wastewater treatment field. Instrument USES the large screen graphics LCD display, temperature measurement and display the DO value and medium at the same time, has two analog signals output and field bus communication interface. Simple Chinese menu operation greatly convenient user use.
Features of EDO industrial dissolved oxygen sensor :
1. Large LCD display with backlight display
2. Oxygen can also show different display mode (PPB, PPM, %), temperature;
3. All kinds of data are password protected, to avoid wrong operation;
4. Polarographic oxygen electrode, the electrode performance is stable, reliable measurement
5. Electrode zero point stability, drift small;
6. The electrode response fast (98% < 60 seconds)
7. History curve function: every 5 minutes automatic storage measurement data at a time, can store a month of continuously measuring value;
8. Notepad functions: notepad record the usage and operation of the instrument alarm time, easy to manage.
9. Monitoring electrodes function: each calibration approach, time, and the results were recorded, is advantageous for the query, analysis, electrode change rule
