Mid Level Chlorine Test Strips

Description The Mid-Level Chlorine test strip provides an easy way to accurately measure Free Chlorine in increments of 0, 25, 50, 100,and 200ppm. This test strip produces a distinct colour change over the entire range from blue to brown to orange. This is a great alternative to our Chlorine Test Paper as it is a more accurate measurement of free chlorine. Our Chlorine test paper is only a semi-quantitative measurement, meaning it changes darker shades of one colour (purple). Immerse the test strip in the sample and remove immediately. Hold strip level (do not shake off excess sample). Compare to the colour chart between 5 and 10 seconds after removing the strip from the sample.
