Product details:

Titrator for Chloride. It's simple. Just Dip and compare. No need to carry expensive and bulky equipment around. Features a measuring range of 30 - 600 ppm Cl, in 10-20 ppm increments. When the titrator is placed in an aqueous solution to be tested, fluid will rise up the stip by capillary action. A color change will occur on the strip, the height of which is proportional to the concentration of analyte present.
