*3: Measurement cannot be performed correctly when the electrical conductivity falls below 8 mS/m (80
μ
S/cm). Be
sure to perform measurement in the above conditions.
*4: If the electrode is exposed to the direct sunlight, the anode and cathode electrode could deteriorate. Install the
instrument where it is not exposed to direct sunlight (indoors).
*5: If a reducing agent or oxidizer exists in a sample, it affects the reading. Do not use a sample containing a reducing
agent such as thiosulfate or sulfite, or oxidizer such as O
3
, hydrogen sulfide or chlorine dioxide, as measurement
cannot be performed correctly.
