Top 10 Hanna Fluoride Low Range Checker

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. Accuracy at 20 degree C: +/-0.05 ppm +/-5% of reading. Light Source: LED at 575 nm. Light Detector: silicon photocell. Environment: 0 to 50 degree C (32 to 122 degree F); RH max 95% non-condensing. Battery Type: (1) 1.5V AAA. Auto-off: after two minutes of non-use and ten seconds after reading. Dimensions: 81.5mm x 61mm x 37.5mm (3.2″ x 2.4″ x 1.5″). Method: adaptation of SPADNS method.

Do you want optimal oral health without fluoride?
CloSYS recognizes that some people just prefer to skip the fluoride so we made a fluoride-free version of our great paste. CloSYS Fluoride-Free Toothpaste for sensitive mouths has a unique combination of ingredients like naturally activated Clorastan, a powerful antimicrobial, that kills the harmful bacteria that cause plaque buildup but without fluoride. It’s recommended by leading dental professionals to promote healthy gums, whiten teeth and provide long-lasting breath protection.

The HI772 Checker®HC (Handheld Colorimeter) provides a simple, accurate, and cost-effective way to measure alkalinity in degrees of carbonate hardness, commonly abbreviated as dKH. Critical to marine environments, alkalinity not only provides the carbonate ion required for calcium carbonate skeletal regeneration of coral reefs, but it also acts as a pH buffer against large changes in acidity. Designed as a more accurate alternative to chemical test kits, the HI772 provides quick, accurate results in a few easy steps.
Features at-a-glance:

Easier to use and more accurate than chemical test kits
Dedicated to a single parameter
Small size, big convenience

The HI 701 is a portable handheld meter for measuring chlorine in natural, waste, recreation, and drinking waters.

The HI 701 bridges the gap between less accurate chemical test kits, and expensive professional test instrumentation. To use, zero the instrument with your water sample, then add the reagent. Place the vial into the checker, press the button and read the results within seconds.

The meter has a range of 0.00 to 2.50 ppm (mg/L) + or – 3% of the reading (+ or – 0.03 ppm (mg/L) at 25 degrees C, with resolution 0.01 ppm (mg/L). It operates in temperatures from 0 to 50 degrees C (32 to 122 degrees F)/RH max 95%. The device operates on one 1.5V AAA battery, with an auto-off function that shuts off the device after two minutes of non-use. Dimensions are 81.5 x 61 x 37.5 mm (3.2 x 2.4 x 1.5”) and it weighs 64 g (2.25 oz.).

Chlorine is a common disinfectant for water, and ensuring proper levels is important in many situations. Chlorine colorimeters are used for monitoring quality control in many applications such as swimming pools, sanitation, and drinking water.
