Hanna HI739-11 – Fluoride High Range Checker HC
The Hanna HI739-11 Fluoride High Range Checker HC is a reliable, handheld colorimeter designed for measuring fluoride concentrations in water from 0.0 to 20.0 ppm. Ideal for use in industrial, municipal, or environmental settings, this device offers lab-quality accuracy in a portable and affordable format.
Instead of interpreting color changes by eye, users receive precise digital readings powered by a proven SPADNS method, ensuring greater consistency and confidence in every test.
Key Features
High Range Fluoride Detection
The HI739-11 measures fluoride levels from 0.0 to 20.0 ppm, making it suitable for testing treated water, industrial effluents, and high-fluoride environments.Accurate and Consistent
With a resolution of 0.1 ppm and an accuracy of ±0.5 ppm ±5% of reading at 25°C, the Checker HC delivers reliable performance under real-world testing conditions.Standardized Method
It uses an adaptation of the SPADNS method, as outlined in the Standard Methods for the Examination of Water and Wastewater, 18th edition. This ensures results are in line with recognized analytical standards.Simple and User-Friendly
With just one button for operation, even non-technical users can perform tests quickly and easily. Additionally, the compact design and digital display make field testing efficient and straightforward.Battery-Saving Auto-Off
To extend battery life, the Checker HC automatically powers down after 10 minutes of inactivity.
