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.

Weighs only 2kg

Featuring ADC?€?s highly accurate miniaturised infrared gas analyser and surface mount technology, the LCi-SD weighs only 2kg, a fraction of the weight and size of most traditional photosynthesis systems. Full functionality, flow control, graphic display and data capture is contained within the ultra compact and rugged LCi-SD console.

The LCi-SD is light enough to be carried and operated using a shoulder strap or even worn on a belt.

10 hour battery

Powered by a single, small 12V rechargeable battery and incorporating the latest in low power consumption components, the LCi-SD will function continuously for up to 10 hours between charges.

Designed for prolonged reliable operation in harsh field conditions, the LCi-SD maintains optimal experimental performance even in high humidity and dusty climates.

Miniaturised analyser in chamber head

For over four decades ADC have been world leaders in the design and manufacture of infrared gas analysers (IRGA). ADC BioScientific has now developed a miniaturised format of their proven, portable IRGA. The gold-plated IRGA, housed inside the LCi-SD plant leaf chamber, provides accurate, fast, reliable and stable gas exchange performance. By housing the gas analyser directly in the leaf chamber head, response delays in gas exchange measurements are effectively eliminated. The proximity of the chamber and the analyser also reduces the risk of gas hang-up or water vapour drop out in long lengths of gas tubing.

Long-term stability

The miniaturised IRGA carries out an automatic zero in the standard operational cycle, ensuring long-term measurement stability. This auto-zero cycling time has been reduced in the LCi-SD to significantly improve system response without any loss in analyser stability. All CO2 measurements are automatically compensated for atmospheric pressure, temperature and the affects of water vapour broadening and dilution.

The novel differential in time IRGA design removes the need to constantly balance dual IRGA systems to prevent the calibration of the two cells drifting apart.

High quality environmental sensors

To provide the researcher with full photosynthesis data the LCi-SD plant leaf chamber encloses a number of high quality environmental sensors. Two highly accurate laser trimmed humidity sensors provide exceptionally reliable transpiration data, while high calibre sensors measure Photosynthetic Active Radiation (PAR) and chamber temperature.

The LCi-SD offers the user a choice of accurate leaf temperature determination methods. A new, innovative, self-positioning sensor is provided as standard in many chambers. Alternatively, a manual placement sensor can be employed or the proven Energy Balance equation can be used with any chamber.
