In today's global industrial landscape, simple steady-state salt spray testing (ASTM B117) is no longer sufficient to predict the real-world lifespan of advanced materials. As a leading OEM Cyclic Corrosion Chamber Supplier, we recognize the shift toward Cyclic Corrosion Testing (CCT). Unlike traditional methods, CCT exposes samples to a series of different environments—salt fog, humidity, dry-off, and controlled temperature—in a repeating cycle.
This "Information Gain" approach to testing mimics natural atmospheric conditions more accurately, providing manufacturers with critical data on synergistic degradation factors. Whether for automotive coatings, aerospace alloys, or electronic components, CCT is the gold standard for quality assurance in the age of high-performance engineering.
CCT offers a higher correlation to outdoor corrosion than conventional salt spray, reducing time-to-market for R&D teams.
Our chambers meet international standards including ISO 9227, ASTM G85, Prohesion, and VDA 621-415.
Programmable logic controllers (PLC) allow for seamless transitions between wet, dry, and humid cycles without manual intervention.
Dongguan Huanyi Instruments Technology Co., Ltd. was established on March 20, 2007, covering an area of 6,022 square meters. It is a high-tech enterprise integrating R&D, production, sales and after-sales service.
