Safe Swim® reagent - Combined Chlorine (DPD-3) - 100 strips

Safe Swim® Combined Chlorine Strips test chlorine levels from 0.00 to 12 ppm to keep your pool or hot tub water clean and safe. High combined chlorine levels are the cause of the harsh "chlorine smell" and eye/skin irritation.

Works only with Safe Swim® - digital water testing for pools and hot tubs  

100 reagent strips per bottle.
