The global cold cathode vacuum gauge market is expected to expand steadily from 2026 to 2035, driven by demand for ultra-high vacuum in semiconductor applications. Asia-Pacific is expected to become the largest market, while supply networks are also expected to diversify across regions.
Global demand for cold cathode vacuum gauges is expanding as of 2026, supported by increased investment in semiconductor manufacturing, thin-film deposition and advanced research infrastructure, while supply networks are becoming more regionally diversified. Cold cathode vacuum gauges include inverted magnetron, extractor and wide-range types, and are suited to high-vacuum measurement in highly corrosive processes and environments where hydrocarbons are undesirable.
By region, Asia-Pacific, led by China, Taiwan, South Korea and Japan, is considered the largest and fastest-growing market, while North America and Europe remain strong in research and specialized applications. Although the supply chain faces constraints in materials and calibration capabilities, factory construction and longer replacement cycles are supporting growth.
The market index is forecast to reach approximately 135 by 2035 (2025=100), with a baseline compound annual growth rate of 3.2%. The five main applications are semiconductor manufacturing, coating and thin-film deposition, research and laboratories, particle accelerators and space-environment simulation, and other applications, with each segment expected to account for a certain share of the market.
