An Insulation Resistance Tester is a specialized instrument used to measure the resistance of insulating materials in electrical equipment, cables, transformers, etc. It typically outputs high-voltage DC and measures leakage current to evaluate insulation performance. In foreign trade, this term is commonly found in the export of electrical instruments, power testing equipment, and industrial products. Usage scenarios include: export customs declaration, product manuals, technical agreements, procurement contracts, and customer inquiries. Note: It is necessary to specify the test voltage level (e.g., 500V, 1000V, 2500V), measurement range, accuracy, and safety certifications (e.g., CE, IEC 61010); different models may comply with different standards. The difference from a 'Hipot Tester' (Dielectric Strength Tester) is that an insulation resistance tester measures insulation resistance values (in megohms), while a hipot tester applies higher voltage to check whether the insulation breaks down. Foreign trade professionals should accurately distinguish between them to avoid quotation or delivery errors caused by terminology confusion.
📝 Examples
1. Our company plans to import a batch of insulation resistance testers from China this year. Please provide models compliant with CE certification and FOB Shanghai quotations. (Note: Buyer inquiry, specifying product name, certification requirements, and trade terms.)
2. According to the contract, the seller shall test each motor with an insulation resistance tester before shipment and attach a test report. (Note: Contract clause, stipulating the use of this instrument for quality inspection and submission of proof.)
💡 Foreign Trade Tips
Foreign trade terms are the foundation of international business communication
Trade practices may vary slightly by country; pay attention when using them
When using terms in contracts, specify the applicable version (e.g., Incoterms 2020)
