Operational Matrix - FLIR Extech ExStik EC400 User Manual

Considerations and Techniques
•
Do not touch the inner surfaces of the conductivity electrodes. Touching the surface
of the platinized electodes may damage and reduce the life of the probe.
•
Store the electrode dry, in the storage cap.
•
Always rinse the electrode in de-ionized water between measurements to avoid cross
contamination of the sample. Double rinsing is recommended when high accuracy is
required.
