The LCi is an ultra compact photosynthesis measurement system. Measurement takes place using a newly developed miniaturised analyser for infrared gas analysis (IRGA) which is housed in the plant leaf chamber. The leaf chamber permits very accurate and reliable CO₂ and water vapour measurements for various types of plants. The LCi is an open system. No large external volume is required because a new buffer application is used that compensates for fluctuations in the concentration of CO₂ in the surroundings. There  is  also automatic atmospheric pressure and temperature compensation for all CO₂ measurements.
The device is operated using a control console, a large LCD touch display and a range of user-friendly menus with which the user can access numerous parameters. Data are stored on removable SD memory cards. Measurements can either be started from the control console or using a push button on the leaf chamber.
The recorded data can be exported via a USB interface or using direct transfer from the SD card to a computer. The data format is compatible with usual spread-sheet software. In addition to the standard leaf chamber (broad model), leaf chambers for narrow leaves, small leaves, conifers, small canopy growth (e.g. lawn), whole plants, fruits and soil respiration are also available.
