Chloride ion online monitoring instrument

Chloride ion online monitoring instrument/Chloride ion concentration detectorCL-3000Measurement principle:

The ion electrode measures the potential of a specific ion in a solution, which is measured with reference to a reference electrode with a constant built-in potential. The difference in activity of the ion in the solution will form a certain potential difference, which is related to the ion concentration. Thus, analyze and measure the ion.

Regarding electrode installation:

Chloride ion online monitoring instrument/Chloride ion concentration detectorCL-3000Correction operation steps:

Connect the machine to the electrode correctly; Prepare two concentrations of ion standard solution（10.0ppmand100ppm）；

1Low concentration correction

Wash the electrode thoroughly with deionized water and use filter paper to absorb the moisture. Place the electrode in10.0ppmIn the standard solution and Stir thoroughly. After the measured values to be displayed have stabilized, zero point correction can be performed. The steps are as follows:

① Press Key screen Appearing on the left side of the upper rowSTANDReminder, accompanied byBUFCompared to standard liquid types（1.00 ppm /10.0 ppm /100ppmor.100%）Alternating flashing[At this time, you can press or ↓ Key to change standard liquid type]；

② Press Confirm the type of standard solution with the key and enter the calibration program.

③ When the upper rowSTANDWhen flashing, it indicates that the instrument is undergoing automatic calibration;

④ WhenSTANDWhen the measurement interface disappears and appears, zero point calibration is completed.

2High concentration correction:

Used for electrodes Deionize thoroughly and wash thoroughly, then use filter paper to absorb dry water;Put in high concentration100ppmIonic standard solution and Stir thoroughly. Slope correction can only be performed after the displayed measurement values have stabilized. The steps are as follows:

① Press key 2 On the secondary screen Appearing on the left side of the upper rowSLOPETips;

② Press The key,SLOPEWhen flashing,Indicates that the instrument is undergoing automatic calibration;

③ WhenSLOPEWhen the measurement interface disappears and appears, the slope correction is completed.

【 Electrode Storage Ionic selective electrodes can be stored in low concentration standard solutions during measurement gaps. If not used for a long time, it must be cleaned thoroughly, covered with a protective cover, protected from direct sunlight, and stored dry.

【 Working environment The electrode needs to work in a flowing liquid (otherwise it will affect the electrode life).
