(Tilaustuote, varmista toimitusaika asiakaspalvelusta)



Checker®HC Handheld Colorimeter - Fluoride High Range


Easier to use and more accurate than chemical test kits SPADNS method ±0.5 ppm ± 5% of reading accuracy Large, easy to read digits Auto shut off


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


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.


The HI 739 Checker®HC is simple to use. In one vial add 2 ml of Reagent A and 8 ml of Reagent B; gently invert 5 times, and wait 1 minute, then zero the instrument with the vial. After zeroing, remove the vial and add 1 ml of sample, gently invert 5 times, wait 1 minute, then insert the cuvette into the HI 739 Checker®HC and press the read button for results.


Order Information: HI 739 Checker®HC is supplied with sample cuvettes with caps (2), reagents for 4 tests, syringe with tip, pipette, battery and instructions.
