Thermal spots on photovoltaic modules, overheating of junction boxes, temperature rise of cable joints, and abnormal heat dissipation of inverters are major hidden dangers that restrict the power generation revenue of power plants and cause fire safety accidents. Traditional manual visual inspection and contact temperature gun temperature measurement have shortcomings such as low efficiency, inability to capture small temperature differences, and difficulty in detecting high-risk points, which cannot meet the normal safety inspection needs of large photovoltaic arrays. Suzhou LAILX focuses on the core pain points of photovoltaic operation and maintenance temperature measurement, and has launched the LX-F100 handheld infrared thermal imaging device, equipped with a high-sensitivity non cooled infrared detector, to achieve precise recognition of small temperature differences of 0.05 ℃. It meets the detection needs of multiple scenarios such as photovoltaic, power, industrial, and building. With a lightweight handheld body, long battery life, and intelligent fault tracking function, it has built a non-contact and efficient infrared temperature measurement and detection system, becoming a standard safety detection tool for power station operation and maintenance personnel.

The LX-F100 is equipped with an imported industrial grade long wave infrared focal plane detector, with a response band covering 7 μ m to 14 μ m, and has extremely strong anti-interference ability against water vapor, dust, and strong light. It can stably collect infrared radiation signals in outdoor sunny days, haze, and mild sand and dust environments. The equipment's thermal sensitivity is as low as 0.05 ℃ @ 30 ℃, which is a leading level in the industry. It can capture extremely weak temperature differences between photovoltaic cells and accurately locate hidden heat spots, local hidden cracking heating, and virtual connection heating faults that cannot be distinguished by the naked eye. The temperature measurement range covers -20 ℃ to 350 ℃, fully adapted to various scenarios such as normal temperature inspection of photovoltaic modules, high temperature detection of distribution cabinet cables, heat dissipation investigation of energy storage inverters, and temperature measurement of HVAC pipelines. The full range temperature measurement accuracy is controlled within ± 2 ℃, and the values are stable without drift, providing reliable temperature data support for fault diagnosis.

The device is equipped with LAILX's self-developed intelligent temperature measurement algorithm, which integrates full screen high and low temperature automatic tracking function. After turning on, it can lock the highest and lowest temperature points in the screen with one click, synchronously mark the temperature value and temperature difference, and match the visible light and infrared image dual screen synchronous display mode. The thermal imaging temperature map corresponds one-to-one with the component real scene image, and the operation and maintenance personnel do not need to repeatedly compare, quickly locking the faulty components and wiring points. Single component scanning and detection only takes a few seconds. The daily inspection efficiency of large ground power stations is more than ten times higher than traditional manual mode, greatly reducing the manpower investment in array inspection. Specially optimized temperature palette for photovoltaic detection, adapted for temperature difference imaging comparison of photovoltaic modules, with clear color differentiation in areas with slight heating, without image discontinuity or temperature difference fusion blur, reducing the probability of operation and maintenance personnel misjudging faults.

The ergonomic handheld body design is fully suitable for long-term outdoor operations. The whole machine is lightweight, with no load-bearing pressure when held with one hand. The anti slip rubber body shell is stable and does not slip when held in high and low temperature environments. The 3.5-inch high-definition color display screen automatically brightens under strong outdoor light, and the imaging image can be viewed clearly in direct sunlight scenes. The layout of physical shortcut keys is reasonable, and temperature measurement, photography, video recording, and parameter adjustment can be operated with one click. Zero based operation and maintenance personnel can proficiently master all functions in ten minutes. The battery life performance has exceeded the upper limit of similar devices in the industry, with a built-in large capacity rechargeable lithium battery. Under standard operating conditions, the continuous temperature measurement time exceeds 15 hours, meeting the needs of all day field power station inspections. Equipped with a fast charging charger, it can complete full charging in two hours. The device supports charging and testing at the same time, and continuous operation in remote and unpowered stations does not need to worry about power outages or shutdowns.

The data storage and intelligent analysis functions meet the requirements of standardized archive management in operation and maintenance. The device has built-in local storage space and supports real-time storage of infrared images and temperature measurement videos. Each imaging photo is automatically embedded with temperature measurement time, environmental temperature, and maximum and minimum temperature numerical watermarks to distinguish inspection data from different arrays and dates. The device supports USB high-speed data export and is equipped with PC analysis software. It can batch read thermal imaging files, draw temperature change curves, count the number of abnormal high temperature points, generate infrared inspection safety reports for photovoltaic power plants, and fully retain the original data of each inspection for long-term power plant temperature rise trend analysis, fault recurrence tracing, and safety acceptance data archiving. The equipment has a protection level of IP54, waterproof, dustproof, and anti fall. It will not be damaged by light rain or gravel impact on the internal precision detection module. The working temperature range is -30 ℃ to 60 ℃, and it can be stably used in high-altitude, desert, and coastal high temperature and high humidity power stations.

In addition to the core scenarios of photovoltaic operation and maintenance, the LX-F100 handheld infrared thermal imaging device has universal detection capabilities for the entire industry. It can be used in the power industry for temperature rise detection of distribution cabinet busbars, cable joints, and transformers; Used in the field of industrial manufacturing for motor bearings, pipeline insulation, and troubleshooting of equipment circuits; Used in the construction industry for wall hollowing, door and window heat leakage, and underfloor heating pipeline positioning; Emergency scenarios can be used for residual temperature detection in fire scenes and troubleshooting of equipment overheating hazards. One device can cover the testing needs of multiple departments, helping enterprises reduce the procurement cost of multiple professional instruments. With the continuous expansion of the domestic photovoltaic stock operation and maintenance market, the requirements for normalized and refined safety inspections of power plants are constantly increasing, and the market demand for high-precision and portable infrared temperature measurement equipment continues to be released. Suzhou LAILX LX-F100 quickly occupies the photovoltaic operation and maintenance equipment market with its four core advantages of ultra-high thermal sensitivity, ultra long battery life, lightweight portability, and multi scenario universality. Relying on a complete national after-sales network, one-year machine warranty, and lifetime algorithm free upgrade service, it has been widely purchased by major new energy groups and third-party safety testing institutions. In the future, LAILX in Suzhou will continue to optimize its infrared detection hardware, iterate the photovoltaic hot spot AI automatic recognition algorithm, further reduce the manual discrimination workload of operation and maintenance personnel, and use domestically produced high-precision infrared detection equipment to assist in the safe and stable development of the clean energy industry.
