pH Calibration
1. Immerse the electrode in pH6. 86 (under the temperature of25℃) standard buffer solution ofphosphate,and gently shake theelectrode.
2. Regulate the trimmer with ascrewdriver until the buffersolution value corresponding tothe measurement temperature isobtained.
3. Immerse the electrode inpH4. 01 or pH9. 18 the standardbuffer solution of borax.
4. After about one minute, untilthe buffer solution valuecorresponding to themeasurement temperature isobtained.
 
Important:
The instruments pH range mustbe re-calibrated whenever.
The electrode has been used (laid)for long time from the last calibration.
