・6122S and 6122SA electrodes are resistant against organic foulants. Inorganic foulants may not be effective.
・Even an organic foulants may not be effective for clean water where algae is likely to grow, or for samples containing solid oils and fats. Also, fine particles of alumina or zirconia may scrape the photocatalyst, the antifouling may not be possible.
・When using this electrode, a relay box with a constant current source (CT-302) and a relay cable (C-5A) are required separately
※1 Composite type pH electrode 6108 is recommended when a high accuracy is required for strong acid and strong alkaline aqueous solutions.
※2 At sample temperatures above 30 °C, the electrode life will be shortened.
※3 An adapter is required when using the 6122S as a drop-in type.
※4 A direct screw-in thread adapter is required when using the 6122SA as a direct insertion type.
