HANNA HI739 HR Tintometer

Introduction

Fluoride is one of the few substances in drinking water that has a great impact on human health. A small amount of fluoride in drinking water is beneficial to human dental health, but excessive fluoride can have very adverse effects on human health. In 1994, a World Health Organization expert committee recommended that the reasonable content of fluoride in drinking water ranges from 0.5 to 1.0 ppm, depending on the climate. Bottled water often has unknown fluoride levels, and some home water filters remove some or all of the fluoride.

HI739 Fluoride HR Colorimeter is designed for fluorideThe handheld Colorimeter designed for concentration measurement is compact in design, easy to use and highly accurate.

Features

Compared with traditional tungsten lamps and other light sources, LED light sources have better performance and higher luminous efficiency. They can use less energy to provide a stable light source. LEDs can ignore the heat they generate because higher heat will affect electronic products. stability.

HANNA's carefully designed CAL CheckTM function allows performance verification and calibration of the instrument using NIST traceable standards; CAL CheckTM NIST curve calibration set is used to simulate specific absorbance values ​​at each wavelength to verify the accuracy of subsequent readings.
