The Standard in

Systems

LCpro-T

Field portable, laboratory grade instrument that offers highly automated photosynthesis

measurement with micro-climate control, RGBW light source and a battery charge that lasts all day.

New features - RGBW light source that allows duplication of solar spectrums or various artificial lamp spectrums for more reliable measurement. Color Touch screen control and color graphing of A/Ci curves and A/Q curves. Now with GPS to record the location of measurements.

 

ADC made the first commercially available IRGA photosynthesis available back in the 1970s. However, over the years, the instrumentation has evolved. The new LCpro‐T is a laboratory grade instrument that is very field portable with an overall weight of under 11 lbs. and a battery charge life of between 8‐16 hours. It’s unique self‐ calibrating IRGA system minimizes instrument measuring errors, and drift errors, while ensuring that it is the easiest to use photosynthesis system available.

Features

The New LCpro-T, with microclimate control, combines many of the advantages of the existing LCpro-SD with improvements from the latest available science and technology.

  • The LCpro-T reduces or eliminates instrument babysitting while providing new capability.
  • Development of powerful RGB LEDs allows researchers to approximate solar spectrums at different times of day, or approximate other actinic light spectrums, providing more reliable A/Q curves and A/Ci curves.
  • GPS location information with every measurement.
  • Color touch screen menu driven adjustment capability.

Advantages of the LCpro SD that still exist on the new LCpro T

  • Auto-zeroing Infrared gas analyzer for calibration of every measurement and +/-1 μmole CO2 measurement reliability
  • Laser trimmed H20 sensors for +/- 1 millimole accuracy without drift, and less instrument babysitting.
  • Humidity control that allows chamber adjustment, not only below ambient but also the unique capability to provide humidity  above ambient and near ambient to reduce instrument babysitting and help prevent leaves from becoming inactive under clamp.
  • Battery charge life of 8-16 hours.
  • Light weight for more enjoyable field work.
  • USB & SD card data transfer up to 32 GB
  • Since 1969, ADC have been world leaders in the design and manufacture of infrared gas analysers (IRGAs). They have consistently advocated the open mode of analysis, whereby a constant flow of air and ambient pressure are maintained throughout the sample chamber. This technique is accepted within the plant science community as the most accurate and versatile operating system for photosynthesis research.

    The LCpro T chamber handle houses an expertly crafted, miniaturised IRGA. Gold-plated by hand, the IRGA provides accurate, fast and stable gas exchange performance. By housing the IRGA directly within the chamber handle, they minimised any possible response delays in either gas exchange measurements or environmental controls. In addition, this configuration reduces gas "hang-up" or water vapour "drop-out", which is known to occur in long lengths of gas tubing.

    The LCpro T IRGA carries out an automatic zero within the standard operational cycle, ensuring long-term measurement stability. All CO2 measurements are automatically corrected for atmospheric pressure, temperature and the effects of water vapor. ADC's novel "differential in time" IRGA design removes the need to constantly balance dual IRGA systems to prevent calibration of the two cells drifting apart over time.

    To provide full photosynthesis data, the LCpro T plant leaf chamber encloses several environmental sensors. Two highly accurate, lasertrimmed humidity sensors provide exceptionally reliable transpiration data. High caliber sensors also measure Photosynthetically Active Radiation (PAR) and chamber temperature. The LCpro T offers a choice of accurate, leaf temperature determination methods. An innovative, self-positioning thermistor 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.
