ES9020 Intelligent Lightning Protection Component Tester, also known as Lightning Protection Component Tester or SPD Field Tester, is a specialized instrument used for performance testing of lightning arresters, lightning arresters, surge protectors, varistors, metal ceramic discharge tubes, and direct air lightning arresters. This instrument adopts a charging function for offline use, overcoming the disadvantages of traditional products that require plug-in use and are inconvenient for on-site operation. It has a wider range of applications with a voltage output of 2000V, uses high-voltage short-circuit protection, automatic discharge function, and is reliable, safe, and durable. At the same time, it has insulation resistance testing function, adopts luxurious large color screen display, data storage, data retrieval, qualification judgment, automatic shutdown, USB data upload and other functions. The whole machine is beautiful and high-end, with a wide range, high resolution, convenient operation, easy portability, accuracy, reliability, stable performance, and strong anti-interference ability.

　　ES9020 also has shockproof, dust-proof, and moisture-proof structures, suitable for harsh working environments. It is a commonly used and essential instrument for meteorological lightning protection, power, postal and telecommunications, communication, electromechanical installation and maintenance, as well as industrial enterprises that use electricity as industrial power or energy. It is suitable for testing the performance parameters of various lightning arresters and surge protectors.

　　The ES9020 intelligent lightning protection component tester consists of medium to large-scale integrated circuits. This meter has a high output power, with a starting voltage measurement range of 0-2000V, a leakage current measurement range of 0.1~199.9uA, an insulation resistance of 0~1000M Ω, good repeatability, and convenient and fast one click measurement.
