  • Model Name: LI3608-SR
  • Product Type: Corded handheld 1D barcode scanner
  • Key Features: Rugged design, fast 1D scanning, multiple feedback modes, advanced linear imager, durable construction

Technical Background

Thermal imagers generate images by detecting the infrared radiation emitted by objects. When objects have different surface temperatures, they emit infrared radiation of varying intensities, which the thermal imager captures and converts into images. The basic principle involves using an infrared sensor to receive infrared radiation from objects, converting it into electrical signals, and ultimately transforming it into visible images. Depending on the application requirements, thermal imagers can be divided into two types: active and passive. Active thermal imagers work by emitting infrared radiation to objects and capturing their reflections, while passive ones only receive the infrared radiation emitted by objects themselves.

Design and Durability

The Zebra LI3608-SR Series Standard Range Linear Imager has an extremely rugged design built to withstand the toughest industrial environments. It has the highest drop, tumble and sealing specifications in its class, withstanding multiple 8 ft drops to concrete and an IP67 rating for dust, spray, and water resistance. Thescanner can even be submerged in water for 30 minutes without damage. It operates in a wide temperature range from -30°C to 50°C. The durable construction ensures a long service life despite rough handling.

Functional Features

Image Enhancement Technology

Thermal imagers are typically equipped with various image enhancement technologies, such as autofocus, digital image processing, etc., to improve image quality and clarity. These technologies can help users accurately identify targets and anomalies, thereby enhancing work efficiency.

Ease of Use

The ease of use of a thermal imager is one of the crucial factors for users’ consideration. Excellent user interface design, simple and intuitive operation processes, and rich functionality settings can greatly improve the user experience and reduce the learning curve.

It provides 30% longer scanning range compared to competitive models. The extra bright aiming pattern ensures accurate capture even on pick lists. The scanner can read barcodes under shrinkwrap, damaged, dirty, or poorly printed.

Technical Parameter Analysis


The resolution of a thermal imager determines the clarity and detail of its images. A thermal imager with high resolution can provide clearer and more detailed images, aiding in accurate target and anomaly identification. Therefore, when choosing a thermal imager, it is essential to consider whether its resolution meets the actual requirements.


The sensitivity of a thermal imager refers to the smallest temperature variation it can detect. The higher the sensitivity, the more accurately the thermal imager can detect minor temperature differences, thereby enhancing its reliability and practicality in various application scenarios.

Temperature Range

Different types of thermal imagers have different temperature measurement ranges, covering various application scenarios from extremely low to extremely high temperatures. When selecting a thermal imager, it is necessary to consider whether its temperature measurement range can meet the requirements of practical applications to ensure its reliability and stability in various environments.
