The HI701 Checker®HC (Handheld Colorimeter) is a simple, accurate and cost effective way to measure free chlorine.

Free chlorine in water is also harmful to a reverse osmosis membrane and needs to be monitored for removal from source water prior to being used. Designed as a more accurate alternative to chemical test kits, the HI701 provides quick, accurate results in a few easy steps.
