GT20 Series

Durable, Heavy-Duty Design

The GT20 Series has a highly durable design to withstand strong impacts. It is environmental resistant due to the IP65 rating and the possible operating temperature between -20 and 50°C. The scanner offer an overwhelming reading performance: LCD screens and poorly printed labels are no obstacles. Besides further additional features, a powerful reading algorithm has been created for high-speed reading.

"Manufactured by the inventor of the QR Code, the GT20 offers impressing features. On the one hand, it is able to scan multiple QR Codes at once. On the other hand, it can read only the targeted code even when multiple codes exist in the reading area."
