Sample Requirements
Electrodes with an epoxy body should only be used in aqueous solutions.
Electrodes with a glass body may be used in
The ORP electrodes contain a silver/silver chloride (Ag/AgCl) reference that may become clogged in solutions that contain silver complexing or binding agents such as TRIS, proteins and sulfides. Frequent cleaning may be required when measuring solutions that contain these agents. Proteins cause the additional problem of coating the electrode, so extra care should be taken to keep the electrode clean while measuring samples that contain proteins.
