HI9772 is an advanced portable pHotometer for the measurement of low levels of fluoride in water. This meter offers a superior optical system that utilizes a reference detector and narrow band interference filters for extremely fast and repeatable measurements.
Fluoride is best known for preventing tooth decay. Water authorities often add fluoride to drinking water to maintain approximately a 1.0 mg/L (ppm) concentration. Fluoride can be found naturally in groundwater, particularly if a reservoir is in close proximity to seawater. While fluoride does help prevent tooth decay, too little can be ineffective while too much can cause staining of teeth.The HI97729 uses an adaptation of the EPA method 340.1 and the Standard Methods for the Examination of Water and Wastewater, 23rd Edition SPADNS method, to measure fluoride concentrations up to 2.00 mg/L (ppm). When the colored reagent is added to samples containing fluoride, the fluoride in the sample will form a colorless complex; the greater the concentration, the clearer the color. The associated color change is then colorimetrically analyzed according to the Beer-Lambert Law. This principle states that light is absorbed by a complementary color, and the emitted radiation is dependent upon concentration. For low range fluoride determination, a narrow band interference filter at 575 nm allows only yellow light to be detected by the silicon pHotodetector and omits all other visible light emitted from the LED lamp. As the change in color of the reacted sample decreases, absorbance of the specific wavelength of light also decreases, while transmittance increases.
CAL CheckAdvanced features including CAL-Check to verify performance and if necessary, recalibrate.
Setup OptionsBacklit dot matrix LCD that offers an exceptionally intuitive user interface that is easy to read and understand.
Tutorial ModeTutorial mode for step-by-step instructions to guide a first-time user in how to perform a measurement correctly.

High Efficiency Light Source:
High Quality Filters:
Greater Light Yield:
A focusing lens collects all of the light that exits the cuvette, eliminating errors from imperfections and scratches that may be present in the glass. The use of the convex lens reduces the need for indexing cuvettes.
