The hot spot effect is a common fault in the operation and maintenance stage of photovoltaic modules. Component obstruction, hidden cracking of battery cells, virtual connection of wiring terminals, and damage to bypass diodes can all cause local abnormal temperature rise. Long term overheating can accelerate the aging of packaging materials, burn out battery cells, and in severe cases, cause the entire string of modules to be scrapped. Traditional manual inspections are difficult to detect subtle temperature rise hazards in advance. The Suzhou LAILX LX-F200 handheld infrared thermal imaging instrument relies on high-precision infrared temperature measurement imaging technology, with the product advantages of non-contact rapid temperature measurement, portability, and intelligent data analysis, to connect the preventive detection gateway of photovoltaic module thermal faults, while also taking into account the use of electrical equipment inspection, industrial equipment temperature measurement, and building energy conservation detection in multiple fields, becoming a cross industry universal precision detection instrument. Compact, portable, precise imaging

The LX-F200 is equipped with a 640 × 480 high-definition infrared detector, with a temperature measurement range covering -20 ℃ to 550 ℃. The temperature measurement accuracy of the whole machine is controlled within ± 2 ℃. The device is equipped with an intelligent temperature difference calculation program, which can customize the environmental reference temperature and automatically calculate the temperature rise value and phase to phase temperature difference of the measured point. It accurately distinguishes between normal heating and abnormal heating caused by faults, avoiding data interference caused by environmental temperature fluctuations. In the photovoltaic inspection scenario, operation and maintenance personnel can use handheld devices to scan up close and visually see the infrared thermal spectrum of components on the screen. The high-temperature and bright areas are the hot spot fault points, achieving early detection and disposal of faults from the root, and avoiding small faults from evolving into irreversible component scrapping problems. Actual test data shows that photovoltaic power stations equipped with LX-F200 for regular inspections have reduced component scrap failure rates by over 70% and reduced annual operation and maintenance costs by more than 30%.

The gripping structure of the product is optimized according to ergonomics, with a net weight of less than 1 kilogram. The compact size of the body makes it easy to carry around, and it is not easy to get tired during long-term handheld operations in the wild; Dual large capacity replaceable lithium batteries for alternating power supply, with a single battery life of up to 3 hours, meeting the needs of uninterrupted field inspection operations throughout the day. The device screen is designed with high brightness, providing excellent outdoor visibility with strong light. It is equipped with a built-in laser positioning auxiliary light spot, which accurately locks the temperature measurement point; Unique image collection and annotation function. If any abnormal faults are found during inspection, they can be marked and archived in real time. The built-in image library classifies and manages the fault images. In the later stage, all abnormal samples can be filtered and exported with one click. The supporting PC data analysis software can batch organize temperature measurement reports and improve the power station operation and maintenance file management system.

In addition to the core application scenarios of photovoltaics, LX-F200 also performs outstandingly in the field of electrical inspection of distribution rooms. It can quickly identify electrical hazards such as cable aging, loose connection terminals, circuit breaker overload heating, and abnormal temperature rise of transformers, helping power operation and maintenance to transform from fault repair to predictive maintenance; At the same time, it is widely used in scenarios such as underfloor heating leakage detection, HVAC pipeline temperature measurement, and industrial motor fault screening, greatly reducing the cost of equipment procurement for enterprises. Thanks to its excellent versatility and reliability, the device has been implemented in multiple industries including new energy, power, metallurgy, and construction, and has gained unanimous recognition from end users in various regions.
The current domestic stock of photovoltaic installed capacity continues to increase, and refined preventive operation and maintenance has become the mainstream trend of industry development.

Handheld infrared thermal imagers, as intelligent inspection equipment, are steadily expanding their market space. LAILX relies on its local R&D and production advantages. Compared with imported products with the same parameters, LX-F200 has higher cost-effectiveness and localized after-sales support. It has technical service outlets in many parts of the country, which can quickly respond to equipment calibration, fault repair, and technical training needs. The future R&D team will continue to optimize detector performance, upgrade algorithms to improve temperature stability in low-temperature environments, continuously expand product application boundaries, and use domestically produced high-quality thermal imaging products to assist in safe and efficient production in various industries, safeguarding the steady development of green energy.
