WHAT does this product do?
Serim® Monitor™ for Chlorine (100-750 ppm) strips measure free chlorine. The test gives a semi-quantitative indication that diluted bleach (sodium hypochlorite) solutions have the appropriate concentration of free chlorine required for disinfecting hard, non-porous surfaces.

WHY should I use this product?
Commonly used household bleach at a 1:100 dilution contains between 400 and 600 ppm free available chlorine.¹
Using a bleach solution in which the free chlorine concentration is too low will not thoroughly disinfect surfaces. However, using an unnecessarily high concentration of chlorine may leave an unhealthy residue or cause metals to corrode. The goal is to develop cleaning/disinfecting methods that effectively rid surfaces of soil and micro-organisms without overusing chlorine.
"Hypochlorite solutions in tap water at a pH>8 stored at room temperature (23°C) in closed, opaque plastic containers may lose up to 40-50% of their free available chlorine level over a period of one month."²
"Fresh solutions of diluted household bleach made up daily (every 24 hours) are considered appropriate for disinfection of environmental surfaces and for decontamination of sites following initial cleanup (i.e., wiping up) of spills of blood or other potentially infectious materials. Contact time for bleach is generally considered to be the time it takes the product to air dry. Solutions of bleach should not be stored in glass containers, but in material such as the plastic in which the bleach, the consumer product, is packaged in."³

WHERE do I use this product?
Serim Monitor strips allow testing at various point-of-use locations where diluted bleach is used as a hard surface disinfectant. Review applicable regulations and manufacturer's recommendation to determine appropriate testing requirements.

HOW TO USE MONITOR™ for CHLORINE (100-750 ppm)
Serim Monitor strips are supplied in ready-to-use, dip and read form. When placed in contact with the sample according to the directions for use (see below), the indicator pad changes color relative to the concentration of free t chlorine. Color blocks are present a 100, 200, 350, 500 and 750 ppm. Note: Test strip cannot distinguish free chlorine concentrations above 800 ppm.

Test Method	Immersion
Test Strip Technique	Immerse indicator pad in sample for a full two (2) seconds. Shake strip firmly to remove excess sample.
Results	At 90 seconds compare the color in the center of the indicator pad to the color chart on the bottle label. Disregard color around the edge of the indicator pad. Note: The test strip cannot distinguish free chlorine concentrations above 800 ppm.
Store bottles of Serim Monitor for Chlorines at temperatures between 15°-30°C (59°- 86°F). The lot number and expiration date are printed on the bottom of each bottle.
