Indigo™ sanitizer test strips for very low to very high levels for all your disinfection needs in restaurants, hospitals, schools, day care, agriculture and more.
Test strips for chemical sanitizers approved for the disinfection of food contact surfaces, hospitals, daycare, cruise ships and more include chlorine, hydrogen peroxide, quaternary ammonium compounds (QACs), peracetic acid & iodine.
Note that the 200ppm chlorine & 50ppm iodine are paper but other specs apply.
Chlorine and quaternary ammonium sanitizers are by far the most important especially in food preparation. The table below lists their pros & cons. Peroxide use is more specialized for things like hot tubs and contact lens cleaners where skin/eye sensitivity can be an issue.
|Effective on a wide variety of bacteria||Can be corrosive|
|Not affected by hard water||Can be irritating to the skin|
|Generally inexpensive||Deteriorates over time|
|Loses some activity in the presence of organic matter|
|Not affected by hard water||Effectiveness decreases greatly with increase in pH|
|Less irritating to the skin than chlorine||Should not be used in water > 50°C|
|Activity is not lost rapidly in the presence of organic matter||May also discolor equipment and surfaces|
|Nontoxic, odorless, colorless, noncorrosive, nonirritating||Slower at killing some microorganisms|
|Relatively stable in the presence of organic matter||Not compatible with some detergents|
|Active over a wide pH range||Not compatible with hard water|
