Product Description

The HI 729 is portable meter for Low Range Fluoride and is ideal for Water Quality. Fluoride is one of the very few chemicals that have been shown to cause significant effects in people through drinking-water. Fluoride has beneficial effects on teeth at low concentrations in drinking-water, but excessive exposure to fluoride in drinking-water, or in combination with exposure to fluoride from other sources, can give rise to a number of adverse effects. Water fluoridation is the controlled addition of fluoride to a public water supply to reduce tooth decay. Fluoridated water operates on tooth surfaces: in the mouth it creates low levels of fluoride in saliva, which reduces the rate at which tooth enamel demineralizes and increases the rate at which it remineralizes in the early stages of cavities. A 1994 World Health Organization expert committee suggested a level of fluoride from 0.5 to 1.0 mg/L, depending on climate. Bottled water typically has unknown fluoride levels, and some domestic water filters remove some or all fluoride. Dedicated to a single parameter. Designed to work with HANNA’s reagents. Uses 10 mL glass cuvettes. Small size, big convenience. Weighing a mere 64 g (2.25 oz.), the Checker HC. easily fits into the palm of your hand or pocket. Use for quick and accurate on the spot analysis. Single button operation: zero and measure. Operated by a single AAA battery. Ideal for water quality. Range: 0.00 to 2.00 ppm. Resolution: 0.01 ppm.
