Maintenance of potentiometric titrator

1. Instrument usage conditions: The ambient temperature and titrant temperature of the instrument should not exceed 35 ℃, otherwise it will cause deformation of the piston in the burette device and affect its use.
2. The socket of the instrument must be kept clean and dry, and must not come into contact with acid, alkali, or salt solutions to prevent moisture and ensure the insulation and high input impedance performance of the instrument. When the instrument is not in use, insert the Q9 short-circuit plug into the socket of the measuring electrode to prevent dust and moisture from entering. When used in places with high humidity, the electrode plug should be wiped dry with clean gauze.
3. It is best to regularly clean the entire burette with distilled water, especially for titrants that may produce precipitation or crystallization (such as AgNO3). After use, they should be cleaned promptly to avoid damaging the valve.
4. When using perchloric acid glacial acetic acid as a titrant, the ambient temperature should be maintained at no less than 16 ℃, otherwise crystallization may occur and the valve may be damaged.
