Mesureur portatif de la surface des feuilles
Modèle CI-203


he CI-203 Handheld Laser Area Meter uses advanced laser technology to enable researchers a precise and convenient way to measure leaf area (or the areas of leaf-like objects). The high-resolution laser scanner, data logger, and display are all enclosed in a single, handheld wand unit weighing 910g. Researchers can perform non-destructive measurements on leaves of living plants by simply pulling a leaf through the instrument, enabling collection of data from the same plant, or even the same leaf, throughout its life span. For rapid measurement of detached leaves, the CI-203CA, conveyor attachment makes a perfect complement to the CI-203.
In addition to the conveyor attachment, the CI-203 also has an optional attachment, CI-203RL for measuring the area of roots and other irregularly-shaped matter. All six measurement parameters (area, width, length, perimeter, shape factor, and aspect ratio) comprise a data set and are compiled at the same time, and over 15,000 data points can be stored and transferred to a computer or printer.

Features
  • Ideal for field use.
  • Non-destructive measurement
  • Measures area, length, width, and perimeter and calculates shape factor and aspect ratio
  • High resolution of 0.1mm²
  • No calibration required
  • Stores up to 15,000 single measurements
  • Easy to use
  • Light-weight and self-contained instrument with built-in data logger and Graphic display
  • Rechargeable battery
  • Measures objects up to 150mm (254mm with conveyor) wide and 25mm thick of virtually unlimited length
  • Conveyor Attachment (CI-203CA) is available for fast measurement in the field or lab.
  • Root Length Measurement Attachment (CI-203RL) is available.
  • RS232 port transfers data to printer or computer.

How to use it
This is as easy as data collection gets. To measure leaf area, simply sweep the leaf through the measuring wand, and the CI-203 instantly scans and calculates the leaf area, width, length, perimeter, shape factor and aspect ratio. The CI-203 is flexible as well as fast: use in the field to measure living leaves on plants one-by-one, or add the conveyor attachment and measure hundreds of individual leaves in minutes. The CI-203 stores over 15,000 data points, and displays data on the LCD screen. Download measurements to a computer later at your leisure via the RS232 port.
