The CI-203 Handheld Laser Area Meter is a portable instrument for the non-destructive measurement of leaf area. The CI-203 can be adapted to have a conveyor for the continuous measurement of a large number of leaf samples. The CI-203 uses advanced laser technology to enable researchers a precise and convenient way to measure leaf area (or the areas of leaf-like objects). The CI-203 has been upgraded to offer a host of new features that will augment data sets and make collection quicker and easier. Through new technology, measurement consistency and repeatability has been vastly improved.

The CI-203 is, without question, the best leaf area meter in the market. We have also improved the instruments ability to accurately measure delicate leaves, including a feature that allows the researcher to see an image after each measurement to insure a successful scan. Built-in GPS tagging adds a location for each data set and the removable SD card provides an easy and fast way to download data to your computer.
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.
The CI-203 collects length, width, perimeter, and area measurements directly using a combination of a sweeping laser beam and an optical motion sensor. After activating the device by pressing the key, a low energy laser beam sweeps across the laser window 500 times per second at a rate of 150 m/s. As the user moves the CI-203 wand down the leaf, an optical sensor records the motion, and the onboard processing unit collects the data. Each laser sweep uses the optical sensor data to correctly accumulate the area and perimeter measurements. When the optical sensor detects that vertical motion has stopped, the laser subsystem stops taking measurements and the processing unit computes and posts the final results.
