In the modern industrial landscape, the longevity of materials is not just a quality metric—it is a critical safety and financial requirement. As a leading Salt Spray Corrosion Test Manufacturer, Dongguan Huanyi Instruments provides the technical infrastructure required to simulate decades of atmospheric exposure in a matter of days. Corrosion costs the global economy trillions of dollars annually; our mission is to provide the "Information Gain" necessary for engineers to mitigate these risks before products reach the end-user.
Salt spray testing (also known as salt fog testing) remains the benchmark for evaluating the corrosion resistance of coated and uncoated metallic surfaces. Whether it is NSS (Neutral Salt Spray), AASS (Acetic Acid Salt Spray), or CASS (Copper Accelerated Salt Spray), our chambers are engineered to maintain a precise micro-climate. The precision of salt fog atomization, the uniformity of temperature distribution, and the strict adherence to ASTM B117 and ISO 9227 standards are what separate high-quality manufacturers from entry-level suppliers.
Experience matters. With over 20 years in environmental simulation, our R&D team doesn't just build boxes; we build precision scientific instruments that allow for repeatable, reproducible results—the cornerstone of scientific validation in the automotive, aerospace, and electronics sectors.
Advanced PID control systems ensuring temperature fluctuations stay within ±0.5°C, providing the stability required for long-term validation.
Constructed from high-density PVC or PP sheets to resist the corrosive internal environment, ensuring a lifespan of 15+ years for the chamber itself.
Meeting ASTM, ISO, JIS, and GB standards out of the box, facilitating international trade and certification for your products.
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. We are proud to have participated in the drafting of national standards (GB standards) and industry standards for environmental simulation test equipment.
Our philosophy is "customer-centric, quality-guaranteed, honesty-based, and innovation-oriented". Through unremitting efforts, Huanyi has cultivated a high-quality team with rich production, R&D and management experience.
With the persistent efforts of all staff, our products have been selling to Southeast Asia, Europe, the United States, the Middle East and other regions, and have gotten excellent feedback from customers worldwide.
From digital sheet metal processing to final assembly, everything is handled in-house. This reduces lead times by 30% compared to international competitors.
Our proximity to high-tech component suppliers allows us to iterate and launch new models, like IoT-enabled chambers, faster than anywhere else on earth.
We pass the savings of scaled manufacturing on to you, offering high-precision equipment at 40-60% of the cost of European or American brands without compromising on components.
High Quality Control from every aspect of raw material, production, installation, and commission. We use internationally renowned brand components to ensure performance.

NSS (Neutral Salt Spray) uses a 5% NaCl solution and is the standard for most metals. AASS (Acetic Acid) adds glacial acetic acid to lower the pH, making it more aggressive for decorative coatings. CASS (Copper Accelerated) adds copper chloride and is specifically designed for high-performance coatings like chromium on plastics or steel.
We use a specialized quartz glass nozzle that prevents clogging and a tower-style spray system that ensures the fog is dispersed evenly across the chamber without direct impingement on the samples.
Yes, our chambers are specifically engineered to meet and exceed ASTM B117, ISO 9227, and JIS Z 2371. Each unit undergoes rigorous calibration before leaving the factory.
We provide comprehensive digital support, including video installation guides and remote diagnostics. For large-scale installations, our technical team is available for on-site commissioning and training through our global partner network.
Our main components are sourced from internationally renowned brands to ensure long-term stability and performance. Our independent innovation capabilities have led to the launch of several domestically advanced test instruments.
