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.
