Description
Handheld Laser Leaf Area Meter CI-203 from CID Bio-Science
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.
- Graphic display and rendering of leaf images for verification of a successful scan and auditing of data
- Built in GPS tagging to provide location data for each measurement
- Non-destructive measurements
- No calibration required
- One-Touch Data: Simply sweep the CI-203 over a leaf to yield six measurement parameters: area, width, length, perimeter, shape factor, and aspect ratio
- Durable and lightweight
- Improved consistency of measurements
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 at a time. 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 USB port or SD card.

Theory of operation
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.
