The Standard in
Plant Stress Measurement
Systems
LCi-T
Highly Portable Ambient Photosynthesis System (IRGA) with touch screen control.
Measures all types of plant stress at an affordable price.
The LCi-T 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, with minimal training.
Features
- Very Easy to use - automated IRGA zero calibration and other automated housekeeping functions allows reliable use with minimal training
- Ultra compact - weighs only 2kg (5lbs).
- Measures CO2 to +/-1 μmol or +/- 1 ppm
- Measures H2O to +/- 1 mmol or 1000 ppm
- IRGA near the measuring chamber
- USB and removable 32 GB SD data card data output
Also measures:
- Leaf temperature
- Chamber temperature
- Barometric pressure
- Q (PAR or light level)
The LCi-T is a highly portable ambient photosynthesis measuring system (IRGA). 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 mmol. The range for CO2 measurement is 0-2000 μmoles or ppm, and the range for H2O measurement is 0-75.5 mmols or mbars. The system has an auto-zero calibration that occurs after every photosynthesis measurement. The instrument reports "A" or photosynthetic rate, "E" or transpiration and "Gs" or stomatal conductance. Measured values are corrected for atmospheric pressure and IRGA drift with every measurement.
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.
