Portable Leaf Area Meter

Great data without harming the plant

The LI-3000C Leaf Area Meter is a lightweight, non-destructive instrument to get leaf area measurements where you need to.

Ideal for rapid field surveys of attached leaves at a single point in time, or throughout their life cycles, the LI-3000C measures the area, length, average width, and maximum width of each leaf. Measurements are displayed on the digital readout as data are taken and recorded in the on-board memory for subsequent analysis.

You can save a record for each leaf, or group records so that they represent the total for each plant or treatment group.

Simple, fast data collection

Ease of use and versatility make the LI-3000C an excellent choice for rapid field survey measurements.

To measure a leaf, open the scanning head and close it over the leaf, near the petiole. Grasp the length encoding cord and then draw the scanning head over the leaf, so the apex of the leaf passes through the scanning head.

The LI-3000C measures leaf area using narrow-band light emitting diodes (LEDs) and paired detectors in the scanning head. LEDs and detectors encode the width, while the encoding cord encodes the length. The instrument computes length, width, and area from these data.

Large numbers of detached leaves can be efficiently measured using the LI-3000C Portable Area Meter in combination with the LI-3050C Transparent Belt Conveyer Accessory.


LI‑3050C Transparent Belt Conveyor Accessory

In the laboratory, the LI-3050C can be used to make fast and accurate measurements of detached leaves.

The LI-3050C Transparent Belt Conveyer Accessory converts the LI-3000C into a bench-top area meter capable of quickly scanning detached leaves. In this configuration, the LI-3050C provides a motor-driven conveyer that rapidly moves leaves through the scanning head of the LI-3000C. The LI-3000C measures the area and records data to its internal memory or directly to an attached computer.
