7 Important information on the calibration
- Before and after immersing the electrode into a pH solution, rinse it with distilled water.
- Calibrate each pH solution twice, if possible.
- It is recommended to calibrate in two steps: pH 7 first, followed by pH 4, then calibrate pH 7
again and then pH 10.
- If the calibration solution deviates by 2 pH, “ERR”will appear in the display.

12 Disposal
For the disposal of batteries in the EU, the 2006/66/EC directive of the European Parliament
applies. Due to the contained pollutants, batteries must not be disposed of as household waste.
They must be given to collection points designed for that purpose.
In order to comply with the EU directive 2012/19/EU we take our devices back. We either re-use
them or give them to a recycling company which disposes of the devices in line with law.
For countries outside the EU, batteries and devices should be disposed of in accordance with
your local waste regulations.
If you have any questions, please contact PCE Instruments.
