Sample Dimensions:
Width: 127 mm maximum, 1 mm minimum
Thickness: 8 mm maximum
Length: 1 meter maximum
Scanning Speed: Up to 1 m/s. Length encoding cord drawing speed need not be constant. Error message indicates if encoding cord is drawn too fast.
Power Requirement: Rechargeable 6V lead-acid battery; or 115/230VAC, 50/60 Hz, 20W maximum
Battery Capacity: Typically 12-15 hours of continuous operation
Recharging Time: 5-8 hours, instrument off; charging circuitry is built in
Battery Voltage Sensor: Low battery warning occurs approximately 1 hour before automatically shutting off the instrument. Over-voltage warning occurs if battery becomes over-charged.
Scanning Head:
LED Light Source: 6.4 mm from outer edge

Weight: 2.0 kg (4.4 lb)

The LI-3000C 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.
