What LibertyCES's vendor documentation shows

Signet's verbatim application list for this family names Fruit and Vegetable Washing, Poultry and Meat Processing, Food and Beverage, and Gray Water Dechlorination — food-industry-specific instrumentation, not generic water. Critical constraint to carry onto the page: the 2630 electrode must not be used in water containing surfactants, oils, organic chlorine or cyanuric acid stabilizers, and produce-wash water frequently carries surfactants and oils. Also note the 4632's reagent-free ClO2 measurement — no consumable reagent stream to manage in a food plant.
