CHEMICAL RATINGS
INTERFERENCES
Alcohols >5%; hydrogen peroxide > 3%; sodium
hypochlorite (commercial bleach) > 3%; gaseous
sulfur dioxide; gaseous chlorine. Do not use in organic
solvents (e.g., acetone, chloroform, methylene chloride,
etc.), which may swell the sensing element (foil matrix)
and destroy it.
