It is small enough to be used to take measurements while the leaf is attached to the plant and is capable of measuring several parameters of the leaf. The meter can perform non-destructive measurements including area, length, width, and perimeter. The accumulated area function will total the area of two or more measurements. An RS232C port transfers data to a printer or computer. The unit consists of a control unit with LCD display, microprocessor, software, data cable, battery pack, charger, scan board, and a hand held scanner.
Operation is relatively simple.
To measure, place the leaf under the clear plastic on the scan board. Push and hold the button on the side of the scanner as you slowly move the scanner over the leaf. Stored data can be sent to a computer or printer with the supplied cable. The cable is connected to the serial port of the receiving unit. Threshold is adjustable with a roller switch on the side of the scanner.
