Page 13: Calibration
Calibration We recommend to operate at least a 2-point calibration. If you can only perform a 1-point calibration, please make sure the buffer value is very closed to the sample you are measuring and the buffer temperature must be stable enough. -

Always keep pH probe wet when in storage. The probe is well protected by a plastic bottle with soak solution in it. To use the probes, rotate the bottle and remove the bottle away from the probe. pH probe can be stored in a 3M KCL solution. Never use distilled water for storage. - Page 16 • Make sure the measurement is processed in container. • Clean or re-calibrate or replace with a new probe • Move to another room and try again , it is supposed that the unstable reading is caused by strong RF interference field. The reading is not changed •...
