Product Description

The Hanna Instruments HI 96729C low-range fluoride colorimeter kit is a handheld device using an advanced optical system to measure the amount of fluoride in a water sample after a reagent is added.

To take a reading, simply fill the cuvette with 10mL of water, add 2mL of the fluoride reagent, and press “read”. The meter uses a tungsten lamp light source, and a silicon photocell with a narrow band interference filter to detect the amount of fluoride present.

The factory-calibrated meter features Hanna Instrument’s Cal-Check validation function, which ensures the meter is properly calibrated, and includes instructions on how to easily recalibrate, if necessary. The meter is water- and dust-resistant, and includes a special locking feature to ensure the cuvette is properly in place for each reading.

The HI 96729C uses an adaption of EPA method 340.1 and Standard Methods for the Examination of Water and Wastewater, 20th edition, SPADNS method. The meter measures fluoride content in the 0.00 to 2.00 mg/L (ppm) range (+ or - 0.03 mg/L + or - 3% of reading at 25 degrees C) with a resolution of 0.01 mg/L. It operates on one 9V battery, and automatically shuts itself off after ten minutes.

Fluoride colorimeters are used for measuring the amount of fluoride present in drinking water and other water sources. Fluoride exists in groundwater from the natural weathering of rocks, from agricultural run-off, and is also sometimes added to drinking water to prevent tooth decay. Fluoride meters are used to ensure appropriate levels of fluoride are present in drinking water, agricultural run-off, and in food and beverage manufacturing.

Hanna Instruments manufactures a wide variety of analytical instrumentation, including pH meters, multi-parameter meters, electrodes, chemical reagents and buffer solutions. Founded in 1978, Hanna is headquartered in Woonsocket, RI, with subsidiaries in 32 countries. Hanna Instruments holds many firsts in the field of analytical instrumentation, including a pH electrode with a built-in temperature sensor, an electronic pocket-sized pH tester, and a replaceable electrode pH pocket tester. To ensure the quality of their products, Hanna is a vertically integrated manufacturer and does not subcontract any part of its manufacturing.

Verified Purchase
I am in the water filtration business, and purchased this unit to help me quickly measure the effectiveness of my water filters at removing fluoride from tap water. Since laboratory testing on each sample can be over $40, and I need to test many samples a week, I figured I'd just purchase this $300 meter and save on testing in the long run.


1. Too much of a hassle to get a simple reading, and the product description on Amazon doesn't mention that the meter as it comes is incomplete, and additional supplies need to be purchased to use this meter:

a. Need to purchase liquid reagents (which stain most things they touch in a red color).
b. Instructions advise to purchase a chlorine remover (as chlorine in water may interfere with reading).
c. Instructions advise to obtain a Class A Pipette to properly measure reagents.
d. The meter requires you to prepare a de-ionized water "Zero-out" solution for proper use.
e. The "Automatic" Pipette supplied with unit did not come with instructions and is poorly made.
f. Need to wait 2 minutes before analyzing each sample.
g. Cuvettes come with tightly sealing plastic caps which are difficult to remove when need to fill a new sample. (Need to use a knife or nails to pull it off).
h. The unit requires a specific sample temperature range to make effective measurements. (I think from 64-78F), yet it doesn't measure temperature of the solution, so you need to also ensure you're measuring the temperature of every sample before testing it.

In scientific experiments and analysis, one of the major obstacles to overcome is the Errors.
