VIDEO: CIRAS-3 reaches stability in 21 seconds! More data in less time.

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

Actual Photosynthesis Measurement in 21 Seconds with the CIRAS-3 Portable Photosynthesis System!

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.

Create Rapid A vs Ci Curves with the CIRAS-3 Portable Photosynthesis System

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.

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 CO ₂ 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.

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.... Read more
