CIRAS-3 Operation Manual V. 1.09 36 support@ppsystems.com
Section 2. What’s new with CIRAS-3?
Much has changed since we introduced the CIRAS-1 Portable Photosynthesis System back in 1992.
What you will find in CIRAS-3 is not only a simple repackaging of existing designs and concepts, but in
many cases a complete rethinking of both the form and function available through CIRAS-3’s hardware
and software. Below you can read a summary of those changes, many of which are based on direct
feedback from our customers. Many more details will emerge throughout this manual.
General Changes to CIRAS-3 Hardware
Main Console
• The CIRAS-3 main console has been significantly redesigned – it is now exceptionally light at 4.5
kg (including 2 battery packs), with new, more compact dimensions of 28 cm (Width) x 15.5 cm
(Depth) x 24 cm (Height) footprint.
• The sealed console has a transflective color display with a practical 30° ergonomic design.
• The console has greater processing speed and larger data storage capability than previously.
• Reference and Analysis gas connections are through a single, integrated connector/port.
• New gas tubing with better absorption characteristics has replaced older tubing associated with
the console and cuvette.
• The CO
2
regulator assembly is improved, eliminating the need for the internal “O” ring.
• The console handle is adjustable by continuous tension over 180°, eliminating fixed positions that
required both hands to set.
