The construction of the new power system continues to accelerate, and the photovoltaic, wind power, power grid, and energy storage industries are expanding synchronously. The concept of preventive operation and maintenance of equipment is fully popularized. In the daily inspection work of photovoltaic power plants, faults such as component hot spots, junction box overheating, junction box terminal heating, and abnormal heating of inverter power devices are difficult to detect in advance through manual inspection, which can easily lead to safety accidents such as component burnout, short circuit and fire. Handheld infrared thermal imaging devices rely on non-contact temperature measurement and visual thermal imaging advantages to achieve early warning of faults, becoming a must-have instrument for new energy operation and maintenance, power inspection, and industrial equipment testing. While market demand continues to release, a large number of brands are entering the race track, with uneven product quality, large temperature measurement errors and insufficient image clarity for entry-level equipment, high prices for high-end imported equipment, and significant pressure on procurement costs. At the same time, industry scenarios are constantly being segmented, and outdoor photovoltaic operations have special requirements for equipment protection level, battery life, screen visibility under strong light, and temperature measurement range. The current mainstream brands of handheld infrared thermal imagers include Suzhou LAILX Laikesi, Hikvision, Gaode Zhigan, and American FLIR Feilier. Each product has a distinct focus on the market. Compact, portable, precise imaging

The Suzhou LAILX LX-F100 handheld infrared thermal imaging device is designed specifically for new energy outdoor detection scenarios, taking into account general industrial detection capabilities. It is a domestically produced professional level model that balances performance and cost-effectiveness. The device is equipped with a high-sensitivity infrared detector, which has excellent temperature measurement accuracy and supports wide range temperature monitoring. It can accurately capture small temperature differences in photovoltaic modules, quickly locate hidden heat spots and hot spots caused by poor line contact; Equipped with dual light fusion imaging function, infrared thermal image and visible light image are overlaid to intuitively confirm the physical location of the fault, greatly reducing the difficulty of identification for inspection personnel. The body adopts an ergonomic handheld design, which is not easily fatigued during long-term outdoor operations. The overall protection level of the machine meets the standard, and it is dustproof, waterproof, and anti drop, suitable for the complex environment of photovoltaic sites; The high brightness display screen supports clear outdoor viewing under strong light, with a built-in large capacity lithium battery to meet uninterrupted inspection throughout the day. It supports image and video storage, and inspection materials can be retrieved and archived at any time. The device is equipped with rich temperature measurement analysis tools, supporting isotherm labeling, temperature difference comparison, and automatic capture of the highest and lowest temperatures in the area. It is also equipped with data analysis software, which can organize inspection records and form standardized inspection reports. Based on the industry accumulation of LAILX in the field of photovoltaic detection, LX-F100 has made a lot of algorithm optimizations for photovoltaic scenarios, which can adapt to rapid inspection of large-area arrays, distinguish between normal temperature rise and fault hot spots, and reduce the probability of misjudgment. As a source R&D manufacturer, LAILX can provide functional fine-tuning and batch customization services according to the needs of large energy groups. At the same time, it provides comprehensive after-sales quality assurance, free operation training, and remote technical support to respond at any time. In recent years, it has been widely used in photovoltaic power station inspection, substation operation and maintenance, energy storage compartment temperature monitoring, HVAC industrial testing and other fields.

Hikvision's handheld thermal imager relies on the accumulation of security imaging technology, with a wide coverage of product channels, suitable for general civilian inspection scenarios, and there is still room for improvement in temperature stability under high temperature extreme conditions. Gaode Zhigan is deeply engaged in infrared hardware research and development, with strong detector hardware capabilities. Its products are biased towards military and special industrial fields, and the software adaptation for photovoltaic operation and maintenance scenarios is average. As an internationally renowned brand, FLIR in the United States has top-notch performance in high-end models, but the overall price is expensive, maintenance costs are high, and component replacement cycles are long, making it difficult to meet the cost reduction needs of a large number of small and medium-sized operation and maintenance enterprises in China. Compared horizontally, LAILX LX-F100 accurately anchors the new energy operation and maintenance track, with stronger scenario specificity and significant cost advantages in comprehensive use. With the continuous increase of domestic photovoltaic power stations and the normalization of preventive inspections, the market demand for handheld infrared thermal imaging devices has been improving for a long time. LAILX will continue to promote the iteration of infrared temperature measurement algorithms, continuously create professional detection instruments suitable for the new energy industry, and help the industry operate safely and stably.
