103 Factory & 100 Custom Methods: Provides immediate options and flexibility with pre-set and customizable methods.
Vial Barcode Reader: Increases accuracy and efficiency with automatic vial scanning and identification.
The HI802 automatically identifies barcoded sample vials, detecting method type and range to minimize errors and streamline measurements.
Vial rotation during measurement enables method identification and multiple absorbance readings, which are converted to concentration units and displayed on the LCD. This rotational averaging improves method accuracy.
Single-zero measurement with DI water blank correction ensures stable readings and reflects sample features, not instrument changes, for ease of use.
The 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.
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 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.
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.
The 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.
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.
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.
