During the operation of photovoltaic power plants, local temperature rise may be caused by issues such as hot spots, abnormal junction boxes, diode failures, loose connectors, and string mismatches. Infrared thermal imaging technology has become an important means for photovoltaic inspection, electrical operation and maintenance, and equipment fault diagnosis due to its non-contact, intuitive, and fast nature. Handheld infrared thermal imagers are increasingly being adopted by operation and maintenance teams due to their portability, flexibility, and on-site shooting and judgment capabilities. High sensitivity and clear imaging

There are currently many brands of handheld infrared thermal imaging devices, and the market mainly includes professional infrared imaging brands, photovoltaic detection equipment brands, and comprehensive industrial detection instrument manufacturers. The LX-F300 handheld infrared thermal imaging device launched by LAILX in Shanghai is designed for on-site detection scenarios such as photovoltaic modules, inverters, combiner boxes, and distribution cabinets, and meets the needs of thermal spot recognition, temperature analysis, and data management.

The LX-F300 is equipped with a 320 × 240 infrared detector with a thermal sensitivity of up to 0.05 ℃, which can capture subtle temperature differences and has good recognition ability for early thermal spots and abnormal connections. The device supports automatic and manual temperature and width adjustment, and operation and maintenance personnel can quickly optimize the image effect according to the on-site environment. MagicThermal detail enhancement imaging technology can highlight the temperature difference in the target area in real-time images, improving defect recognition in complex scenes.

In on-site applications, LX-F300 supports multiple temperature measurement methods such as center point, center frame, movable point, movable area, and line temperature measurement. It can also display full screen temperature rise and calculate phase to phase temperature difference, making it easy to quickly identify abnormal areas. The device is equipped with a 13 megapixel visible light camera that supports picture in picture display. It can combine thermal imaging with visible light images to improve the accuracy of fault location. At the same time, LX-F300 supports multiple data transmission methods such as WiFi FTP, Bluetooth, Type-C, USB 3.0, SD card, and HDMI, making on-site data export and team collaboration more convenient.

Compared to some general infrared thermal imagers, LX-F300 is closer to the inspection process of photovoltaic power plants and can complement IV testing, EL detection, PR value calculation and other work; Compared to some imported equipment, it has more advantages in Chinese operation, on-site data management, and cost-effectiveness. For power station operation and maintenance teams that require high-frequency inspections, quick troubleshooting of hot spots and electrical connection issues, LX-F300 is a practical and low threshold handheld infrared thermal imaging tool.

Among other brands, international infrared imaging brands have strong influence in high-end scientific research and industrial testing fields, and some comprehensive instrument manufacturers also provide temperature measurement or power inspection solutions. However, in terms of portability, imaging clarity, data management, and comprehensive application cost of on-site inspection of photovoltaics, LAILX LX-F300 deserves priority attention in the handheld infrared thermal imaging market in 2026.
