Ideal for rapid check of residual chlorine levels in water samples
Detects chlorine as hypochlorus acid (HClO) or the hypochlorite ion (ClO-)
Chemically-treated paper strips change color and can be easily used in the lab or out in the field
These test strips are perfect for quickly estimating residual chlorine levels as hypochlorus acid (HClO) and hypochlorite ions (ClO-) in samples treated with sodium hypochlorite (NaClO). Easy to hold strips are 1/4" W x 1.5" L (7 x 40 mm) — simply dip a strip into your sample, wait 60 seconds, and compare the color change of the strip to the chart on the bottle.
