As one of the major inorganic anions in water and wastewater, chloride is often measured in a variety of industries. Due to its corrosive nature, chloride levels are monitored in boiler systems and cooling towers to prevent metal parts from being damaged. Not known to be toxic to humans, chloride is monitored in drinking water for aesthetic purposes due to its negative affect on taste. However, chloride can be toxic to plant life. Chloride may be monitored in agricultural applications in certain areas of the world where salinity levels are known to be naturally high.

The HI97753 uses an adaptation of the mercury (II) thiocyanate method to measure chloride concentrations of less than 20.0 mg/L (ppm). When both the mercury (II) thiocyanate and iron-based reagents are added to samples containing chloride, the sample will turn an orange hue; the greater the concentration, the deeper the color. The associated color change is then colorimetrically analyzed according to the Beer-Lambert Law.

This principle states that light is absorbed by a complementary color, and the emitted radiation is dependent upon concentration. For chloride determination, a narrow band interference filter at 466 nm (blue) allows only blue light to be detected by the silicon photodetector and omits all other visible light emitted from the LED. As the change in color of the reacted sample increases, absorbance of the specific wavelength of light also increases, while transmittance decreases. Using a pre-programmed curve a result is then displayed.

The HI97753 has an innovative optical system that offers superior performance in accuracy, repeatability, and the short amount of time it takes to perform a measurement. This compact, waterproof meter is extremely user friendly with a tutorial mode that walks the user graphically, step by step, in performing a measurement. The use of a backlit dot matrix LCD allows the use of virtual keys which makes the operation of the meter very intuitive including selecting different units of measure, reviewing GLP data, recalling the last 50 measurements, and customizing the meter to user preferences.
