HANNA Free Total Chlorine Checker, Each

The HI701 Checker® Handheld Colorimeter offers a straightforward, precise, and cost-effective method for measuring free chlorine. Free chlorine, the active variant employed for disinfecting drinking water, swimming pools, spas, and vegetable rinse water, plays a crucial role in various applications. Additionally, it is essential to monitor free chlorine levels in water to safeguard reverse osmosis membranes, as its presence can be detrimental.

Serving as a superior alternative to chemical test kits, the HI701 ensures swift and accurate results through a user-friendly four-step process. Distinguishing itself from chemical test kits and high-end professional instrumentation, the Hanna Free Chlorine Checker® strikes a balance.

While chemical test kits rely on the human eye, providing limited accuracy, professional instrumentation, although highly accurate, can be expensive. The HI701 bridges this gap by utilizing a fixed wavelength LED and a silicone photodetector, combining the accuracy of professional instrumentation with the affordability of a chemical test kit. The device's compact, portable design, built-in timer, and one-button operation further enhance its practicality and convenience.
