HI97779 is an advanced portable photometer for the measurement of chlorine dioxide in water. This meter offers a superior optical system that utilizes a reference detector and narrow band interference filters for extremely fast and repeatable measurements.   No warm up time before taking a measurement Tutorial mode for step-by-step instructions CAL Check to verify meter performance Used primarily as a disinfectant in drinking water and in various industrial processes, chlorine dioxide is a highly effective, environmentally friendly microbiocide. Chlorine dioxide is safe, potent, and does not produce trihalomethanes, the disinfection byproduct characteristic of chlorine use. The HI97779 uses an adaptation of Standard Methods for the Examination of Water and Wastewater, 23rd Edition, 4500 ClO2D to measure chlorine dioxide concentrations of less than 2.00 mg/L (ppm). When the chlorophenol red reagent is added to samples containing chlorine dioxide, the purple hue from the reagent will lessen. The greater the concentration, the greater the discoloration. 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 chlorine dioxide determination, a narrow band interference filter at 525 nm allows only green-yellow light to be emitted and passed through the sample cuvette. 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 HI97779 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. HI97779 is completely waterproof including the cuvette holder that is designed with ridges to protect the optical path from getting scratched by the cuvette and a gasketed battery compartment that holds three common AA batteries.

The reference detector monitors the intensity of light and modulates when there is drift due to power fluctuation or the heating of the optical components. Each part has an important role in providing unparalleled performance from a photometer.       High Efficiency LED Light Source An LED light source offers superior performance as compared to a tungsten lamp. LEDs have a much higher luminous efficiency, providing more light while using less power. They also produce very little heat, which could otherwise affect the optical components an electronic stability. LEDs are available in a wide array of wavelengths, whereas tungsten lamps are supposed to be white light (all wavelengths of visible light) but actually have a poor blue/violet light output. High Quality Narrow Band Interference Filters The narrow band interference filter not only ensure greater wavelength accuracy (+/- 1 nm) but are extremely efficient. The filters used allow up to 95% of the light from the LED to be transmitted as compared to other filters that are only 75% efficient. The higher efficiency allows for a brighter, stronger light source. The end result is higher measurement stability and less wavelength error. Reference Detector for a Stable Light Source A beam splitter is used as part of the internal reference system of the HI83300 photometer. The reference detector compensates for any drift due to power fluctuations or ambient temperature changes. Now you can rely on a stable source of light between your blank (zero) measurement and sample measurement. Large Cuvette Size The sample cell of the HI83300 fits a round, glass cuvette with a 25 mm path length. Along with the advanced optical components, the larger size of the cuvette greatly reduces errors in rotation from the indexing mark of the cuvettes. The relatively long path length of the sample cuvette allows the light to pass through more of the sample solution, ensuring accurate measurements even in low absorbance samples. Focusing Lens for Greater Light Yield Adding a focusing lens to the optical path allows for the collection of all of the light that exits the cuvette and focusing the light on the silicon photo detector. This novel approach to photometric measurements cancels the errors from imperfections and scratches present in the glass cuvette eliminating the need to index the cuvette.   SKU HI83399-02 Product Name Water & Wastewater Multiparameter (with COD) Photometer and pH meter - HI83399 Quote Required Yes pH Range Photometer pH Resolution Photometer pH Accuracy Photometer pH Calibration Automatic one or two point calibration with one set of standard buffers available (4.01, 6.86, 7.01, 9.18, 10.01) pH Temperature Compensation Automatic (-5.0 to 100.0 oC; 23.0 to 212.0 oF); limits reduced based on the pH electrode used pH CAL Check (electrode diagnostics) clean electrode and check buffer/check probe displayed during calibration pH Method Photometer pH-mV Range ±1000 mV pH-mV Resolution 0.1 mV pH-mV Accuracy ±0.2 mV Dissolved Oxygen Range 0.0 to 10.0 mg/L (as O2) Dissolved Oxygen Resolution 0.1 mg/L Dissolved Oxygen Accuracy ±0.4 mg/L ±3% of reading Dissolved Oxygen Measurement Method Adaptation of the Standard Methods for the Examination of Water and Wastewater, 18th edition, Azide modified Winkler method Absorbance Range 0.000 to 4.000 Abs Absorbance Resolution 0.001 Abs Absorbance Accuracy +/-0.003Abs @ 1.000 Abs Alkalinity Range Freshwater Alkalinity Resolution 1 mg/L Alkalinity Accuracy ±5 mg/L ±5% of reading Alkalinity Method Colorimetric method Aluminum Range 0.00 to 1.00 mg/L (as Al3+) Aluminum Resolution 0.01 mg/L Aluminum Accuracy ±0.04 mg/L ±4% of reading Aluminum Method Adaptation of the aluminon method Ammonia Range Low Range Ammonia Resolution Low and Medium Range Ammonia Accuracy Low Range Ammonia Method Adaptation of the ASTM Manual of Water and Environmental Technology, D1426-92, Nessler method Anionic Surfactants Range 0.00 to 3.50 mg/L (as SDBS) Anionic Surfactants Resolution 0.01 mg/L Anionic Surfactants Accuracy ±0.04 mg/L ±3% of reading Anionic Surfactants Method Adaptation of the USEPA method 425.1 and Standard Methods for the Examination of Water and Wastewater, 20th edition, 5540C, Anionic Surfactants as MBAS Bromine Range 0.00 to 8.00 mg/L (as Br2) Bromine Resolution 0.01 mg/L Bromine Accuracy ±0.08 mg/L ±3% of reading Bromine Method Adaptation of the Standard Methods for the Examination of Water and Wastewater, 18th edition, DPD method.
