DETALLE DE SISTEMA DE FOTOSINTESIS PORTATIL MODELO LCi-SD

 



Marca: ADC

Modelo: LCi-SD

No. Catálogo: LCi-SD

 

DESCRIPCIÓN:

Ultra compact and field portable

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.

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.

 

New LCi-SD graphic

Display

 

All real time photosynthesis data, calculations and

graphs are clearly presented on the new LCi-SD large,

high definition, graphic display.

Parameters may be plotted against time or record

number enabling measurement trends to be easily

monitored and observed. Two parameters may also

be plotted against each other, such as in the case of

light response curve experimentation.

In addition to classical photosynthesis and

transpiration calculations, the LCi-SD provides soil

respiration calculations, including NCER, when the

soil chamber is employed.

 

Unlimited data storage

 

The LCi-SD features unlimited data storage. All experimental protocols,

photosynthesis data and calculations are stored on easily exchangeable Secure

Digital (SD) cards. Use of these widely available cards allows separate cards to be

used for individual users or for specific experimental applications.

Data recording can be initiated both automatically and manually. Automatic data

recording can take place at timed intervals, synchronised to the same point of the

measurement cycle. Alternatively manual recordings can be made either via the

keypad or the button on the chamber handle.

Downloading of data is directly from the SD cards, via RS232 or through the USB output.
