Highly Portable Ambient Photosynthesis System that is easy to use and measures CO2 to +/- 1 μmol
The LCi-SD is our smallest, lightest and most user-friendly portable photosynthesis measurement system ever. It allows access to field sites previously considered unsuitable for conventional gas exchange systems.
The LCi-SD is a portable ambient photosynthesis measuring system. This system is very easy to use yet repeatable, accurate and reliable. CO2 is measured to 1 ppm or 1 μmole, and H2O is measured to 0.1 mbars or 1 mmole. The range for CO2 measurement is 0-2000 μmoles, and the range for H2O measurement is 0-75.5 mmoles. The system has an auto-zero calibration that occurs after every photosynthesis measurement. Measured values are corrected for atmospheric pressure and IRGA drift. Various special measuring chambers are available for Arabidopsis, conifers, narrow leaves, and soil respiration. Flow rate is adjustable, PAR is measured, leaf temperature is measured, and battery charge life is at least 8 hours.
