Photosynthesis measurements can be performed in SECONDS with the CIRAS-3. See for yourself!

How does the CIRAS-3 reach stability so fast?

The CIRAS-3 is a true differential gas analyzer featuring 4 independent, non-dispersive infrared gas analyzers for both CO 2 & H 2 O. It's small system volume is optimized for the fastest, most accurate measurement of photosynthesis available. More data. Less time. #RedefiningPortability Experience less site disturbance and easier access with CIRAS-3’s compact 4.5kg console (including both Li-ion battery packs) and 0.75kg cuvette.

Field measurements become an entirely new research experience.

Ultra-Fast A/C i Curves in minutes! Experience the CIRAS-3’s proven game-changing technology and technique that is generating the fastest & easiest measurements available.

Measure photosynthesis & chlorophyll fluorescence simultaneously Our CFM-3 Chlorophyll Fluorescence Module does double duty as both a fluorometer (PAM) and independent light source — saving you time, space and cost while you measure Fm' using our unique “MultiPulse™ technology. You're in control Fully automatic, independent and programmable control of CO 2, H 2O, light and temperature – one of the widest temperature control ranges and the most reliable in the industry. Highly Referenced The CIRAS-3 is highly referenced in peer-reviewed published papers and journals, many of which are available on-line.  We have some listed on our site for your convenience.

Is the CIRAS-3 easy to learn & use?

The CIRAS-3 is a very popular instrument in my lab. Its intuitive interface has made it easy for the graduate students to learn how to use it. Light and CO 2 response curves are easy to measure, as are regular leaf gas exchange measurements. The CIRAS-3 has been very reliable and provides consistent data. We are excited to have it available in the lab. — Dr. Marc van Iersel University of Georgia

Easy to use. Highly intuitive. Minimal training is needed. Begin collecting data shortly after your system arrives. Built-in system help dialogs guide even the most inexperienced user every step of the way. ...So many plug & play accessories: Several leaf cuvettes & head plates are available for both leaf gas exchange and chlorophyll fluorescence measurement Insect respiration Soil CO2 efflux Net canopy flux Use your own chambers! The CIRAS-3 Portable Photosynthesis System can also be used as a stand-alone CO2 and H2O differential gas analyzer. Learn More about the Ultra-Fast, Highly Portable CIRAS-3 TODAY!

We would love to learn more about your research and possibly work together on an application note highlighting your own research!

Light Spectrum Affects Maximum Rate of Carboxylation & Electron Transport s | APPLICATION NOTE LED lighting not only significantly reduces electricity costs for many greenhouse operations, they offer good efficacy, longevity, and control, and can provide narrow wavebands of light — offering unique opportunities for growers to manipulate crop physiology by changing light spectrum and intensity. These rapidly advancing technologies require a better understanding of the effects of light spectrum and intensity on crop photosynthesis, growth, and development....
