Hanna Instruments HI711 Total Chlorine Checker® HC
The Hanna Total Chlorine Checker® serves as a transitional tool between inexpensive chemical test kits and sophisticated equipment. Chemical test kits rely on the human eye to distinguish changes in hue, which limits their accuracy and resolution.
To precisely determine ion concentration, professional instrumentation combines a light source, such as an LED or tungsten lamp, with a filter and a light sensing detector. Professional instrumentation might cost hundreds of dollars but provides superior resolution and precision.
The Hanna Total Chlorine Checker® offers the precision of specialized equipment at the cost-effective pricing of a chemical test kit by utilizing a fixed wavelength LED and silicon photo detector.
- Compact, Portable Design
- Built-in Timer
- One-Button Operation
To evaluate total chlorine, use the HI711 Checker® HC (Handheld Colorimeter), which is easy to use, precise, and economical. A common disinfectant used in municipal water, produce, and equipment for the food and beverage industry is chlorine.
Despite being helpful in eliminating infections, concentrations above 4 parts per million (ppm) are dangerous to humans and must be watched carefully.
The HI711 was created as a more precise substitute for chemical test kits and offers prompt, precise results in four simple steps:
Features at-a-glance:
- Easier to use and more accurate than chemical test kits
- Dedicated to a single parameter
- Small size, big convenience
- Ideal for: Water Quality, Education, Pool and Spa
