1、 Equipment functional adaptability

1. The BEST-380 multi material compatibility testing capability supports volume/surface resistivity detection of solid, liquid, and powder materials. It is designed using the three electrode method to avoid leakage errors during liquid testing and meets the analysis needs of Sitong Testing for diverse samples.
   

2. Coverage of military and industrial standards
   The equipment strictly follows domestic and international standards such as ASTM D257 and GB/T 1410-2006, meets the high temperature/radiation resistance environmental testing requirements of military materials (such as carbon fiber reinforced resin), and adapts to the certification needs of Sitong Testing in the material field.

3. Intelligent data management
   It has the function of generating testing reports that comply with ISO, IEC and other standards with one click, which improves the data processing efficiency of third-party testing institutions.

2、 Regional cooperation network support

• Cooperation foundation in Shandong region:
  Beiguang Jingyi has completed multiple equipment deliveries in Shandong by 2025, including:

• Litong Xifa (Qingdao) New Materials Technology (March 2025)

• Shandong Taikai Electrical Insulation Co., Ltd. (January 2025)

• Qingdao Yunlu Advanced Materials Technology Co., Ltd. (February 2025)
  

3、 Reference for cooperation mode of similar testing institutions

Taking Hunan Shengshi Rubber Industry Technology (cooperation in April 2025) as an example:

• Procurement combination: BEST-380 resistivity tester+voltage breakdown tester+dielectric constant tester. Effect: Shorten the R&D cycle and optimize production process quality control through high-precision detection. This mode can be extended to third-party detection service scenarios of Sitong Detection.
