Celebrating over 35 years.
Quality Instrumentation for the Life Sciences

Our Proud History

PP Systems is considered a world leader in the manufacture and design of instrumentation for the plant and soil science communities. Our experience in photosynthesis measurements over the past 30+ years has yielded state-of-the-art instrumentation and unsurpassed performance without sacrificing portability. We currently offer the CIRAS-3 Portable Photosynthesis System for high-level research and TARGAS-1 Portable Photosynthesis System for basic research and teaching.

The Evolution of the CIRAS Family of Systems

Our CIRAS family of systems have been incredibly popular with researchers throughout the years. The CIRAS-1 system was introduced in 1992 and was the first system to feature CO2 control (using mini CO2 cartridges) and H2O. The CIRAS-2 system followed in 1999 and it was the first system to feature integral, simultaneous measurement of photosynthesis and chlorophyll fluorescence.

CIRAS-3… Defining “Portability” for High-level Research Worldwide

Introduced in 2013, the CIRAS-3’s mobility and advanced design is the result of numerous discussions and research performed by some of the world’s most prominent photosynthesis experts. Our CIRAS-3 is the high-level field researcher’s instrument and the perfect choice for measurement of:

  • Photosynthesis
  • Chlorophyll Fluorescence
  • Soil Respiration
  • Canopy Assimilation
  • Insect Respiration

For high-level research that demands mobility, the CIRAS-3 is your instrument.
