BEST-300CConductive material resistance tester

1、 Scope of application

The four terminal testing method is currently the most advanced testing method, mainly aimed at testing products with high-precision requirements; This instrument is widely used in production enterprises, universities, and research departments, and is an important tool for inspecting and analyzing the quality of conductor and semiconductor materials.

This instrument is equipped with various measuring devices to test the conductivity of different materials. LCD display, no need for manual calculation, with temperature compensation function, automatic selection of conductivity unit, BEST-300C material conductivity tester automatically measures and automatically switches range based on test results, without the need for manual multiple and repeated settings. Optional: Equipped with software that can be controlled by a computer, and can save and print data, automatically generate charts and reports.

This instrument adopts a 4.3-inch large LCD screen display, which simultaneously displays resistance value, resistivity, square resistance, conductivity value, temperature, pressure value, and unit automatic conversion. Different test fixtures can be configured to meet the testing requirements of different materials. Testing fixtures can be selected according to product and testing project requirements

Provide interface options in either Chinese or English to meet the needs of both domestic and international customers
