This rotational averaging improves method accuracy.Shared single-zero measurementSingle-zero measurement with DI water blank correction ensures stable readings and reflects sample features, not instrument changes, for ease of use.  Spectral rangeThe meter features a spectral range of 340nm to 900nm allowing for a wide selection of analytical methods. The flexibility of this range permits compliance with many methods from regulatory organizations and associations for a variety of applications.Advanced split–beam optical system.In a spectrophotometer the optical system is the heart of the instrument. Ensuring that the optical system is built with the best design and highest quality materials will guarantee accurate readings and a long life for the meter. When developing this meter our research and development team payed special attention to details and combined many small improvements to a typical spectrophotometer design to create a portable meter with unprecedented performance.The convenience of pre-programmed methods with the option to expand.The HI802 comes with over 100 pre-programmed methods for chemical analysis. Methods can be updated via computer or flash drive, and up to 150 can be saved. It also provides reagent codes for easy ordering.Easily access your favorite methods directly from the home screen to save time.Program up to 100 custom methods with up to 10 calibration points, 5 simultaneous wavelengths, and 5 reaction timers. This flexibility allows for extensive customization beyond factory presets, accommodating specific needs and modifications.Universal cuvette holdThe cuvette holder accommodates 22 mm round and 5 cm path length rectangular cuvettes, with adapters for 13 mm, 16 mm, and 10 mm cuvettes, including a 13 mm vial adapter with a barcode reader. It allows selection of cuvette size in custom methods and displays the size on screen for accurate measurements. Worry free replacements.iris uses a tungsten-halogen lamp for greater energy efficiency, longer service life, and improved light quality for a wide variety of wavelengths. Replacement lamps are shipped pre-aligned and ready for installation so that you can get back to testing.Designed for dynamic environments.The meter features a rechargeable lithium ion battery that lasts for approximately 3,000 measurements (excl. vial rotation). Lasting well over a day of use in the field there is no need to worry about the battery life while out working without a power supply. The meter can be quickly recharged with a dedicated fast charging adapter. Quality data without the hassle.Export your results with a USB drive or direct PC link organized by sample ID, method, or date range. Save data as a .pdf or .csv for maximum data integrity or flexibility – all without the use of specialized software.Menu navigation that makes sense.Quickly navigate between screens with custom keys, and access your favorite methods directly from the home screen with our “favorite methods” feature.Sort and share your data.Save data as a .pdf or .csv for maximum data integrity or flexibility. Have the freedom to choose the file format that's best for you. ParameterRangeResolutionAccuracyWavelengthMethodReagent CodeAlkalinity0 to 500 mg/L (as CaCO₃)1 mg/L±5 mg/L ±5% of reading at 25 °C610 nmBromocresol GreenHI775-26 Reagents for 25 testsAlkalinity, Marine0 to 300 mg/L (as CaCO₃)1 mg/L±5 mg/L ±5% of reading at 25 °C610 nmBromocresol GreenHI755-26 Reagents for 25 testsAluminum0.00 to 1.00 mg/L (as Al³+)0.01 mg/L±0.04 mg/L ±4% of reading at 25 °C530 nmAdaptation of the Aluminon MethodHI93712-01 Reagents for 100 tests;
