CI-202 Pallet Leaf Area Meter

The CI-202 Portable Laser 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 approximately 1.5 Kg.

The CI-202 Portable Laser 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 approximately 1.5 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
  • Precise and accurate
  • Fast, non-destructive measurements
  • Durable and lightweight
  • Ideal for field use
  • Stores over 8000 data points
  • Download data to computer

The CI-202 directly measures length, width, area, and perimeter through 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.
