How It Works
The HI739-26 reagents use the proven SPADNS colorimetric method. When fluoride reacts with the SPADNS reagent, it forms a colorless complex that reduces the color intensity proportional to fluoride concentration. The HI739 Checker HC measures this color change photometrically and displays the precise fluoride concentration.
Testing procedure:
- Add 2 mL of SPADNS reagent to two clean cuvettes
- Add 8 mL of the second reagent to one cuvette (blank)
- Add 8 mL of sample to the other cuvette (test)
- The Checker HC analyzes the color difference and displays results in ppm

Applications
Essential for high-range fluoride monitoring in municipal water treatment plants, industrial wastewater treatment, drinking water fluoridation programs, environmental compliance monitoring, aquaculture water quality control, semiconductor manufacturing, pharmaceutical water systems, and laboratory fluoride analysis where concentrations may exceed typical low-range testing capabilities.
Why High-Range Fluoride Testing Matters
Fluoride monitoring is critical in water treatment for both public health (optimal fluoridation levels) and industrial processes (corrosion control, scale prevention). The high-range capability (0-20 ppm) is essential for industrial applications, wastewater monitoring, and situations where fluoride concentrations exceed drinking water standards.
What's Included
One HI739-26 reagent kit containing sufficient SPADNS reagents for 30 fluoride tests (0-20 ppm range), complete with lot number and expiration date for quality tracking. Compatible exclusively with Hanna HI739 Fluoride High Range Checker HC.
