10.2 cleaning of the device
• Activate the HOLD function (see chpt. 9.12.1) in the Calibration menu in order not to interrupt the
process during cleaning.
• Always use a cleaning product compatible with the materials from which the device is made.
• If magnetic particles are in the fluid to be measured, often clean the deposits on the conductivity sensor,
with a special cleaning agent.
• When cleaning the electrodes, ensure that you do not scratch their surface.
• Avoid dry storage of graphite electrodes during long interruptions in measurement in order not to
increase the response time when they are next used.
→
Regularly clean the electrodes on the conductivity sensor with a suitable product, depending on how dirty they are.
Please feel free to contact your Bürkert supplier for any additional information.
