Portable Laser Leaf Area Meter CI-202 from CID Bio-Science

The CI-202 Portable Laser Leaf Area Meter uses advanced laser technology to allow 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, hand-held palette unit weighing under 2 Kg. Researchers can perform non-destructive measurements on leaves of living plants by simply sliding the scanner over the leaf, enabling collection of data from the same plant, or even the same leaf, throughout its life span. Precise leaf area measurement of even tender leaves is possible by employing a transparent sheath for protection.

  • Our most popular leaf area meter

  • No calibration required
  • Stores up to 8,000 single measurements
  • Easy to use
  • Lightweight and self-contained instrument with built-in data logger and LCD display
  • Rechargeable battery
  • Measures objects up to
  • USB port transfers data to computer and charges the device

 

Theory of operation

The CI-202 directly measures length, width, area, and perimeter thru calculating ratio and shap factor after the measurement is completed.

Each time the control unit detects that the scanner has progressed 1 mm, the computer will check to see if the width reading is non-zero.

If the width measurement is non-zero, the computer takes the following actions:

The length measurement is increased by 1 mm.
The width measurement is added to the area accumulator.
If the width measurement is greater than the currently stored maximum width, the maximum width is updated.

 

How to use it

To measure a leaf, simply lift the transparent film, place the leaf on the board, and slide the scanner over the board. The CI-202 yields instant results for leaf area, length, width, perimeter, ratio, and shape factor measurements.
Non-destructive measurement may be performed while the leaf is still attached to the plant.
Over 8,000 data readings can be stored or transferred to a computer.
