With the rapid development of industrial intelligent operation and maintenance and new energy equipment detection, handheld infrared thermal imaging devices have become the core essential equipment for power safety inspection and equipment operation and maintenance. In 2026, the domestic industrial testing industry will fully implement a refined, visualized, and intelligent operation and maintenance mode. The drawbacks of traditional manual inspection and contact temperature measurement methods, such as low efficiency, large errors, and safety hazards, will continue to be highlighted. In this context, the LX-F300 handheld infrared thermal imager launched by Shanghai LAILX has become the preferred device for industrial grade high-precision detection scenarios due to its non-contact, high-precision, and visual detection technology.

The LX-F300 focuses on industrial grade high-precision detection requirements and is equipped with a 320 × 240 pixel high-definition infrared detector with a thermal sensitivity (NETD) of less than 0.05 ℃ @ 30 ℃, which can sensitively capture extremely subtle temperature differences. The device adopts a 5-inch Gorilla explosion-proof touch screen with a display pixel of up to 1280 × 720, supporting touch operation and picture in picture (PIP) function. Its innovative MagicThermal detail enhancement imaging technology can present color thermal imaging of the target area through touch in real-time thermal imaging, while other areas are displayed in black and white thermal imaging, greatly enhancing the imaging effect of subtle temperature differences of specific targets in complex scenes, which is conducive to accurate diagnosis on site.

In terms of intelligent analysis, LX-F300 has powerful native analysis functions, supporting full screen temperature rise display, automatic calculation of phase to phase temperature difference, and partition setting of emissivity, achieving accurate temperature measurement of different materials. The device is equipped with a 13 megapixel visible light digital camera and LED lighting, supporting full standard satellite positioning (Beidou/GPS/GLONASS) and all-round automatic orientation. The position and direction information can be saved to each thermal image. At the same time, LX-F300 supports local recording of full radiation thermal imaging videos and can achieve high-speed data transmission and remote monitoring through various interfaces such as WiFi FTP, Bluetooth, Type-C USB 3.0, etc.

In terms of environmental adaptability, LX-F300 has excellent industrial grade protection capabilities, with a working temperature range covering -20 ℃ to 120 ℃ and an intelligent switching range from 0 ℃ to 650 ℃, suitable for various harsh working conditions. Its compact and portable body design, coupled with a comfortable one handed grip experience, allows it to handle complex outdoor work scenarios such as strong light, high altitude, and narrow spaces with ease. Compared to some civilian or entry-level devices on the market, LX-F300 has demonstrated overwhelming advantages in high temperature resistance, harsh environment resistance, high-precision temperature measurement, and intelligent analysis functions. It can not only accurately locate hidden dangers such as hot spots on photovoltaic modules, overheating of inverters, and abnormal electrical contacts, but also provide solid technical support for the intelligent and all-weather safe operation and maintenance of new energy power plants.
