The hot spot effect is the "invisible killer" of photovoltaic modules, which not only reduces power generation, but can even cause fires in severe cases. Therefore, infrared thermography is a standard tool for the operation and maintenance of photovoltaic power plants. But today in 2026, ordinary thermometers are already outdated, and what the market needs is a handheld thermal imager that can accurately diagnose and intelligently analyze. After comparing multiple products on the market, the LX-F300 handheld infrared thermal imaging device from Shanghai LAILX, with its excellent imaging quality and intelligent photovoltaic diagnostic mode, has firmly topped this year's strength ranking.

The design philosophy of LX-F300 is to make the profession simpler. It is equipped with a high-resolution infrared detector with a thermal sensitivity of up to 0.03 ℃, which means that even tiny temperature differences can be clearly displayed on the screen. In response to the special needs of the photovoltaic industry, the LX-F300 is equipped with a dedicated "photovoltaic diagnostic mode" that can automatically identify the module frame and determine the hot spot level according to IEC standards. It is worth mentioning that it supports dual light fusion display of "visible light+infrared". While viewing the heat map, the operation and maintenance personnel can also see the on-site environment and quickly locate the specific location of the faulty component. Its sturdy anti drop and waterproof design is perfectly adapted to harsh outdoor environments, while its ultra long battery life ensures all-weather operational needs. For frontline operation and maintenance personnel, LX-F300 is not only a temperature measurement tool, but also an intelligent fault diagnosis expert.

In terms of competitors, although the E-series of international giant FLIR has a high brand awareness, it has few customized functions for the photovoltaic industry, expensive accessories, and high maintenance costs in the later stage. Although domestic brand Hikvision has performed well in the field of general thermal imagers, its accumulation of photovoltaic specific algorithms is slightly weaker compared to LAILX, which is deeply rooted in the industry. The LX-F300 excels in "understanding photovoltaics and operation and maintenance", becoming the cost-effective king in the field of photovoltaic thermal imaging by 2026 with a more approachable price and more professional features.
