Superior design for superior results.

Iris can test a wide variety of analytical measurements and is capable of measuring in a spectral range of 340 nm to 900 nm. With the compact design of its advanced optical system, iris can be used in almost any sized space while providing accurate and consistent results. The split beam optical system allows iris to automatically compensate for any drift in light source, resulting in superior accuracy.

No need for measurement conversions.

Whether you are testing for chlorine or running enzymatic assays, our spectrophotometer will conveniently display results in the units that matter most to you. iris can measure in transmittance, absorbance, and concentration based on your need.

The convenience of pre-programmed methods with the option to expand.

iris comes pre-programmed with more than 80 commonly used chemical analysis methods to help you get started. Simply update these methods by connecting to a computer or flash drive.

Customize your iris with up to 100 personal methods. iris will guide you through the method creation process step-by-step. For added versatility, each method can include up to 10 calibration points, five different wavelengths, and up to five reaction timers.

Easily access your favorite methods directly from the home screen to save time.

Built in timers make make measuring seamless. The countdown timer displays the time remaining until a measurement will be taken, ensuring consistent results between measurements and users. If you get stuck, the tutorial mode will walk you through the steps.

Change sample size easily.

With our universal cuvette holder and auto-recognition feature, cuvette sizes can be changed when needed.

The programmed cuvette size will be displayed on the screen every time you test to ensure that the proper path length is being used by the meter when calculating measurements for correct results.

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

Iris' compact profile and long-lasting battery make it easy to set up anywhere in your lab.

The rechargeable lithium ion battery lasts for 3,000 measurements, or 8 hours – well over a full day of use out in the field

All of your important information is easily visible
With a 6” display, the screen is large and easy to read. The high contrast makes every character on the display stand out even during outdoor use. The wide viewing angle allows for measurements to be seen from far away, so while working around the lab it is not necessary to hover over the meter to see the measurements.

Zero resistance with a capacitive touch pad
Menu buttons are part of the display. Built to be fully sealed and easy to clean, the meter recognizes key touches even through gloves.
