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 compact design fits comfortably in the hand for use in the field or on a table for benchtop use.

COD Reactor for Digestion Vials A COD reactor is used to heat the digestion vials. The digestion vials must be heated to a specific temperature for a period time making the HI839800 an important accessory required to have a complete wastewater treatment monitoring system.   Advanced Optical System HI83300 is designed with an innovative optical system that incorporates a beam splitter so that light can be used for absorbance readings and for a reference detector. 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.

HI6321 is a streamlined Conductivity/Resistivity/TDS/Salinity/Temperature benchtop meter with a large touch screen display, comprised of a housing and an integrated conductivity measurement module. HI6321 is a streamlined Conductivity/Resistivity/TDS/Salinity/Temperature benchtop meter with a large touch screen display, comprised of a housing and an integrated conductivity measurement module. Compact and easy to operate, the HI6321 includes Hanna’s HI7631233 four-ring conductivity/ resistivity/TDS/salinity probe. Recommended for a wide range of industrial process water applications, HI7631233 provides stable measurements over a wide measurement range and does not require frequent calibrations. An integral temperature sensor measures the process temperature and adjusts the measured conductivity to a reference temperature by applying specialized compensation algorithms: Linear: appropriate when it is assumed that the temperature coefficient of variation has the same value for all measurement temperatures. Standard: appropriate for high-purity water measurements and documented in ASTM Standard D5391-14. This setting should be used for >1Mohm.cm resistivity measurements. Natural: appropriate for natural ground, well, or surface water (or water with similar composition) in accordance with ISO7888 standard. The result is reliable electrolytic conductivity (EC), TDS (Total Dissolved Solids), resistivity, or Seawater Salinity in percent, psu, or ppt units. TDS is a calculated value based on the conductivity of the solution (TDS = factor x EC25). A TDS factor is a conversion factor used to change an EC measurement to a ppm measurement. Sal psu: The practical salinity of seawater relates the ratio of electrical conductivity of a normal seawater sample at 15 °C and 1 atmosphere to a potassium chloride solution (KCl) with a mass of 32.4356 g/Kg water at the same temperature and pressure. Under these conditions the ratio is equal to 1 and S=35. The practical salinity scale may be applied to values 0 through 42.00 psu at temperatures between 0 to 35 °C. Sal ppt: measurements expressed in ppt are based on the Natural Seawater Scale that extends from 0.00 to 80.00 g/L and covers 10 to 31 °C temperature range. It determines the salinity based upon a conductivity ratio of sample to standard seawater at 15 °C and an approximate salinity value of 35 in seawater. Sal %: in this scale 100% salinity is equivalent to roughly 10% solids.

ISE Measurement with Incremental Methods – The known addition, known subtraction, analyte addition, and analyte subtraction incremental methods are pre-programmed into the HI5522.  Simply follow the on screen guided procedure and the meter will perform the calculation automatically allowing for a higher level of accuracy to be obtained as compared to a direct ISE measurement. Data Logging – Three selectable logging modes are available on the HI5522: automatic, manual, and AutoHold logging. Automatic and manual logs up to 100 lots with 50,000 records max/lot, with up to 100,000 total data points. Automatic logging features the option to save data according to sampling period and interval. Data Transfer – Data can be transferred to a PC with USB cable and HI92000 software (both sold separately). Contextual Help – Contextual help is always available through a dedicated “HELP” key. Clear tutorial messages and directions are available on-screen to quickly and easily guide users through setup and calibration.  The help information displayed is relative to the setting/option being viewed.
