In the long-term operation of photovoltaic power plants, temperature anomalies such as hot spot effect, loose wiring terminals, and overheating of inverters are major safety hazards that can cause equipment failures and even fires. In 2026, as the domestic photovoltaic industry undergoes deep adjustment and structural reshuffle, predictive maintenance (PdM) and fault diagnosis of power stations have become the core links to improve power generation revenue and reduce operation and maintenance costs. The traditional point based temperature measurement method is difficult to fully capture the temperature distribution on the surface of the equipment. However, the LX-F300 handheld infrared thermal imaging device launched by Shanghai LAILX, with its high-precision and intelligent non-contact temperature measurement capability, provides a new solution for the safe operation and maintenance of domestic photovoltaic power plants, becoming the "golden eye" for power plant safety operation and maintenance. High sensitivity and clear imaging

The core advantages of LX-F300 lie in its excellent imaging quality and precise temperature measurement performance. The device is equipped with a 320 × 240 pixel high-sensitivity infrared detector, with a thermal sensitivity (NETD) better than 0.05 ℃, which can sensitively capture extremely subtle temperature differences on the surface of the device. Its innovative MagicThermal detail enhancement imaging technology allows users to display the target area in color thermal imaging through touch in real-time, while the background is presented in black and white, greatly enhancing the recognition of specific targets in complex scenes. The temperature measurement range of the device covers -20 ℃ to 650 ℃, and supports intelligent range switching. Whether it is component hot spots in low-temperature environments or electrical connection points in high-temperature conditions, it can accurately measure.

In terms of intelligent analysis and on-site application, LX-F300 has been deeply customized. The device supports full screen temperature rise display and automatic calculation of phase to phase temperature difference, which can automatically shield environmental temperature interference and help operation and maintenance personnel quickly determine abnormal heating conditions of electrical equipment. The built-in full standard positioning system (Beidou/GPS/GLONASS) and all-round automatic orientation function can save position and direction information to each thermal image, providing accurate geographic coordinates for subsequent fault location and file management. In addition, the device supports AI programmable buttons, automatic naming through QR code scanning, and bookmarking annotations, greatly simplifying the on-site operation process and improving work efficiency.

The data management capability of LX-F300 is equally outstanding. The device supports WiFi FTP wireless data fast transfer, Type-C USB 3.0 wired transmission, and high-speed SD card storage, which can quickly synchronize full radiation thermal images and videos to PCs or smartphones. Users can not only perform real-time analysis of full radiation images and videos on the device itself, but also conduct in-depth diagnosis through professional software, generate visual reports containing temperature data, and provide scientific basis for fault tracing and preventive maintenance.

At present, as the domestic photovoltaic industry accelerates its transition from passive maintenance to active predictive maintenance, LX-F300 is not only a temperature measurement tool, but also a key equipment for safe operation and maintenance of power plants. Through regular inspections and data analysis, the operation and maintenance team can detect potential thermal defects in advance, eliminate safety hazards in a timely manner, avoid power generation losses caused by equipment failures, and help the domestic photovoltaic industry achieve high-quality and safe development in value competition.
