The HANNA HI739 fluoride pocket meter is a digital colorimeter used for fluoride testing.

• Accurate and simple measurements
• Complies with ISO 17381:2012
• Depending on the range:
    - Low range: 0.00 to 2.00 ppm
    - High range: 0.0 to 20.0 ppm

The HI739 comes supplied with 2 cuvettes with caps, reagent for 15 tests, a syringe, battery, instructions, and a quick start guide.

Fluorine is one of the chemical elements that has been shown to affect people through drinking water. Fluoride has beneficial effects on teeth at low concentrations, helping to prevent dental cavities. However, excessive fluoride consumption can also be linked to adverse health effects.

The best current assessment is that adding fluoride to drinking water at concentrations between 0.8 mg/l and 1.5 mg/l does not pose an unacceptable risk to aquatic organisms.

The properties of the fluoride ion remain in water during wastewater treatment, so they do not contaminate the soil or terrestrial ecosystems. Release into the atmosphere from wastewater incineration is also unlikely.

HANNA Checkers

HANNA Checkers are small, portable, and, above all, provide more accurate results than typical chemical test kits. Offering enhanced technology, their simple design allows for easy, hassle-free measurements.

These digital photometers or test kits serve as a bridge between basic test kits and professional instrumentation, such as a calibratable photometer.

Conventional test kits are not precise and depend entirely on the user’s interpretation of color, which is why HANNA has digitized this process and created an accurate, pocket-sized digital colorimeter.

The innovative shape of the Checker fits comfortably in the palm of your hand or your pocket. The LCD screen is easy to read, and the automatic shut-off function helps preserve battery life in case you forget to turn it off.

Easier to use and more accurate than visual test kits:

• Fast, accurate analysis

• Large, easy-to-read digits

• Automatic shut-off

• Dedicated to a single parameter

• Compact size, great convenience

• One-button operation: zero and measure
