These Total Chlorine Test Strips 486670 are used in the Sensafe Exact Micro 7 Photometer and in other water testing micro meters.
Spa and Swimming pool owners should test for total chlorine in pool water regularly to ensure their total chlorine level is in the proper range of 1.0 - 3.0 ppm. When the total chlorine, which includes residual and combined chlorine, exceeds this amount, it can irritate the eyes, nose and skin. If the total chlorine is too low, it may result in the growth of algae and bacteria, which can make your water unsafe and cloudy. Unlike DPD-3 Total Chlorine strips, these DPD-4 Total Chlorine testing strips do not require the use of a DPD-1 strip.
