CIRAS-3 Portable Photosynthesis System Training

PP Systems offers training courses on the CIRAS-3 Portable Photosynthesis System several times throughout the year. Our next course will take place at our Amesbury, MA (USA) office on the following dates:

To be determined

Class size is limited to 5 participants to ensure that everyone receives the maximum benefit of attending the course. The course is designed for the first time CIRAS-3 user as well as those that need a refresher course on the operation and general maintenance of the CIRAS-3 system.

CIRAS-3 Training Course

Day 1

Overview of Gas Exchange – Technology and Applications

  • IRGA technology – basis of leaf-level detection of gas exchange
  • Principles of measurement and open-system design
  • Range and general limitations of applications

Introduction to the CIRAS-3 Portable Photosynthesis System

  • System hardware overview
  • Software – Menu structure and overview
  • Setting up the user and operating environment
  • Getting familiar with measurement display and controls

Performing Leaf Gas Exchange Measurements

  • Initial system checks – electrical/gas connections, chemicals
  • Recording options (Manual and Timed measurements, Response Curves)
  • Designing and running automated Response Curves

Data Management

  • Downloading options – description of formats and data structure
  • Recalculation of data – CIRAS-3 software and spreadsheet options
  • Post-processing, data quality control and data interpretation

Day 2 (Optional)

Participants are invited to stay for a second day of training to include:

  • Simultaneous measurement of chlorophyll fluorescence and gas exchange
  • Closed system applications – soil respiration and whole canopy assimilation with CIRAS-3
  • General CIRAS-3 system maintenance
  • System troubleshooting tips
  • More hands-on time with CIRAS-3


All participants must bring their own system with them in good working condition. If you would like to have your system serviced in advance of the training course, please contact PP Systems as far in advance as possible (30-45 days minimum) to ensure that your equipment is good to go prior to the training course.

Here’s what some customers had to say about the training course…

“The training I received for the CIRAS-2 system was extremely well done. Lots of good practical information and hands-on learning led to my understanding the system well enough to teach others how to use it!” – Sue Dove (University of Georgia)

“The training provided by PP Systems on the CIRAS-2 was exceptional. The training covered aspects ranging from beginner user setup to advanced techniques of chlorophyll fluorescence. The step-by-step instruction made disseminating the knowledge gained with my other lab members quite easy.” – Lauren Pile (Clemson University)
