HI802 iris® visible spectrophotometer quickly identifies Hanna Instruments vial methods by
reading the barcode on reagent vials across multiple methods that support the use of a
single-zero measurement.
The barcode reader for method identification is removable to allow other methods and
cuvette adapters (included) to be used for maximum versatility.
HI802 iris® visible spectrophotometer is portable and allows for measurement in the
spectrum of all wavelengths of visible light and not just pre–specified wavelengths.
Spectrophotometers work by isolating light at specific wavelengths from white light. This
compact meter incorporates a number of features that facilitate both fantastic performance
and exceptional usability.
• Supplied with 103 factory methods
• Create up to 100 user methods
• Automatic method identification of vial samples
• Vial barcode reader
• Shared single-zero measurement across multiple vial methods
• 5 cuvette types (16 mm round, 22 mm round, 13 mm vial, 10 mm square, 50 mm
rectangular) with automatic detection
• Data storage for 9999 measurements with ability to auto log results
• Simplified data transfer to a PC or Mac
• Field upgradeable firmware
• Rechargeable battery

Vial barcode reader for HI802Method identification
Vial barcode reader
Automatic method identification of barcoded sample vials is an exciting feature of HI802.
The HI802 visible spectrophotometer scans an inserted barcoded vial and automatically
detects both method type and method range, significantly reducing the risk of errors and
aiding measurement procedure.

Vial rotation
Vial rotation during measurement allows for method identification and for a number of
absorbance readings. The instrument then converts the readings to concentration units and
the result is shown on the LCD display. This rotational averaging of signals during
measurement (with the lamp on) ensures improved method accuracy.
Shared single-zero measurement
Use of a single-zero measurement across multiple vial methods where blank correction is
done with DI water. This ensures that sample features, rather than instrument changes, are
reflected in the instrument’s measurements and contributes to ease of use and stable

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

Spectral range
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.
Replaceable tungsten–halogen lamp
To be able to measure in a wide variety of wavelengths a broadband light source is necessary.
In the iris® visible spectrophotometer, this is accomplished by a tungsten–halogen lamp. As
these lamps do not last indefinitely, it is necessary to change them throughout the life of the
meter. The pre–alignment of the lighting fixture guarantees that the bulb is in the same
position every time it is changed. This generates peace of mind as there is no need to worry
about realigning the light source.

Concave grating
This element of the optical system is what generates the spectrum of light. When the light
from the tungsten lamp hits the grating it is met with interference coatings that turn the
polychromatic white light into a rainbow. This rainbow contains dispersed light at all
wavelengths in the visible spectrum. The rotation of this grating is what allows for a specific
wavelength to be selected. This ability is one of the biggest differences between a
spectrophotometer and a photometer. The concave grating which accomplishes this is
superior to other types of diffraction, such as prisms, as it minimizes stray light generated and
has constant bandwidth. It also combines elements of the optical system that would typically
be separate, for example if a flat grating was used a concave mirror would need to be added in
order to refocus the light. The combination of these two pieces creates greater efficiency and
a smaller optical system to yield a more compact portable meter.

Beam splitter
The beam splitter is added to the optical system for use with a reference detector to ensure
that the measurement compensates for any drift in the light source. It works by splitting the
light emitted by the tungsten lamp into two beams and sending one beam of light to the
reference detector that measures intensity. If there are any fluctuations in the light source
the meter detects this and compensates through a mathematical calculation. The reference
detector also saves battery life and leads to improved speed of the meter as the lamp doesn’t
have to warm up prior to use.
