Instructions for Micro Moisture Tester:
1. During normal measurement, each 100 ml of reagent can react with no less than 1.5 grams of water. If the measurement time is too long and the reagent sensitivity decreases, the electrolyte should be replaced.
2. For the electrolyte in the cathode chamber, if strong bubbles are released during electrolysis or the electrolyte is contaminated to a light reddish-brown color, the blank current will increase, the linearity of measurement will decrease, and the time to reach the endpoint will be prolonged. In this case, the electrolyte should be replaced as soon as possible.
3. If the electrolysis time exceeds half an hour and the instrument still cannot stabilize, stop stirring and check whether there is obvious brown iodine produced under the platinum mesh below the electrolysis electrode. If there is none or very little iodine produced, the electrolyte should be replaced.
4. To ensure smooth disassembly of various parts on the electrolytic cell bottle, it is necessary to loosen the ground glass joints (including electrodes, drying tubes, injection stopcocks, etc.) at least once a week.
5. The drying tube contains indicating silica gel, which is mainly used to absorb moisture in the air inside the electrolytic cell. If discoloration is found, it should be replaced promptly to avoid an increase in blank current.
6. When replacing the electrolyte, do it quickly because the special ceramic semipermeable membrane under the electrolysis electrode is prone to moisture absorption, which may cause the instrument to fail to reach the endpoint for a long time. Rinse the cathode chamber several times with new electrolyte, then inject new electrolyte and shake a few times until no color change occurs before installing the cell bottle. If the inside of the electrolytic cell bottle is heavily contaminated, clean it with acetone, methanol, etc., especially the inner and outer platinum meshes of the electrolysis electrode and the two platinum claws of the measuring electrode. Clean them thoroughly, then dry in a drying oven at 80°C for 1 hour, allow to cool naturally, and then replace with new electrolyte.
7. It is recommended to use the special electrolyte provided by our factory. Using other brands of electrolyte may result in insufficient accuracy, decreased sensitivity, and the instrument may not reach the endpoint for a long time. Any abnormal operation of the instrument due to this is not the responsibility of our factory.
8. The working environment of the micro moisture tester must be free of corrosive gases, avoid direct sunlight, and the 220V power supply must have a reliable ground wire. It is best to connect an AC voltage stabilizer.
9. The storage temperature of the electrolyte should preferably be below 8°C. In summer, it can be stored in a refrigerator at constant temperature. The shelf life is more than half a year. Use as needed and avoid direct sunlight.
