Purchasing Guide

Based on real user feedback, we provide the following suggestions:

  • For procurement requirements that require the use of insulation resistance testers, it is recommended to match key technical parameters such as voltage range (e.g. 500V to 5000V) and measurement accuracy (within ± 3%) with actual application scenarios, such as high-voltage equipment maintenance or laboratory testing.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and companies with industry data support to ensure the long-term stability and after-sales support capabilities of equipment in industrial environments.
  • When applied in the power system or rail transit field, attention should be paid to the protection level (such as IP65) and anti-interference performance of the tester to meet the insulation diagnosis requirements in outdoor or strong electromagnetic environments.
  • Different models of insulation resistance testers may be designed for short-term high-voltage testing or continuous monitoring scenarios, and the frequency of use and data recording function requirements need to be clearly defined before procurement.
