industry trends

Technological iteration and transformation:

Domestic technology continues to break through, and the performance of some products has approached international standards, but the consistency of equipment and mass production still relies on imports. In the future, we will continue to develop towards higher precision, stability, and reliability.

Domestic substitution acceleration:

Domestic enterprises such as State Power Investment Corporation Hydrogen Energy and Shanghai Carbon International are achieving breakthroughs through independent technology and large-scale production capacity, promoting the industry to shift from foreign led to domestic production.

Application field expansion:

In addition to traditional fuel cell vehicles and energy storage markets, carbon paper is also extending into new fields such as electrolytic hydrogen production and semiconductors, driving the growth of demand for testing instruments.

Ecological transformation of the entire industry chain:

The industry is shifting from single product competition to full industry chain collaboration, and the integration of upstream and downstream will become closer, forming a more efficient industrial ecosystem.

Industry Type

According to technical principles:

Four probe method: used for horizontal resistivity testing, with high accuracy and suitable for laboratory environments.

Four terminal method: used for vertical resistance and contact resistance testing, suitable for rapid detection on production lines.
