LCpro-SD

  • The LCpro-SD is a portable photosynthesis measuring system with fully programmable microclimate control. 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 0-3000 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. It is ideal for A/Ci curves, light curves, and temperature curves. Measured values are corrected for atmospheric pressure and IRGA drift. Various special measuring chambers are available for Arabidopsis, conifers, narrow leaves, and soil respiration. Now available with a white light LED source that that allows chloroplast migration, and the full effects of the xanthophyll photoprotective cycle. Leaf temperature and PAR are measured while battery charge life is about 16 hours.
