Shanghai – TOBO GROUP, a leader in multi-environment testing solutions, is proud to introduce the MultiEnv Salt Spray Tester—a state-of-the-art system designed to simulate a wide range of corrosive conditions beyond traditional salt fog. Catering to industries such as oil and gas, construction, and aerospace, this tester combines salt spray functionality with simulations of humidity, temperature cycles, and chemical exposure, providing a holistic view of material durability in complex real-world environments.
The MultiEnv Tester’s defining feature is its integrated multi-chamber design, which allows for sequential or simultaneous testing across four distinct environmental zones. Each zone can replicate specific conditions: Zone 1 handles standard salt spray (3-5% NaCl solution) at 35°C; Zone 2 simulates high humidity (95% RH) with temperature cycling from 20°C to 60°C; Zone 3 introduces industrial pollutants like sulfur dioxide (SO₂) to mimic urban or industrial atmospheres; and Zone 4 combines salt spray with UV radiation to replicate coastal sunlight exposure. This versatility enables manufacturers to test how materials perform under layered stressors—for example, a pipeline component might first endure salt fog, then high humidity, followed by chemical exposure—mirroring its actual service life. An oil and gas company testing pipeline coatings used this feature to identify a coating that failed under combined salt and sulfur dioxide exposure, preventing potential leaks in offshore rigs.
Precision is maintained across all zones through the tester’s advanced environmental control system, which uses dual sensors per zone to monitor and adjust parameters in real time. Temperature is regulated within ±0.2°C, humidity within ±1% RH, and pollutant concentration within ±5ppm, ensuring compliance with standards such as ASTM B117, ISO 9227, and ISO 6988 (for SO₂ testing). The salt spray distribution system uses variable-pressure nozzles to generate a uniform mist, while UV lamps in Zone 4 deliver controlled radiation intensity (340nm wavelength) to simulate sunlight’s corrosive effects. For construction companies testing steel reinforcements, this precision ensures accurate data on how materials will degrade in both coastal and industrial regions.
Efficiency is enhanced by the tester’s automated specimen transfer mechanism, which moves samples between zones without manual intervention. A robotic arm with soft-grip clamps can transfer up to 30 specimens at once, allowing for continuous testing across different environments. This feature is particularly valuable for aerospace manufacturers, who can test aircraft components through a sequence of salt spray, humidity, and UV exposure to replicate flight conditions over oceans and deserts. A leading aerospace firm reported that using the MultiEnv Tester reduced their multi-condition testing time by 50% compared to using separate chambers for each environment.
Real-world applications highlight the tester’s impact across industries. A manufacturer of wind turbine towers used the MultiEnv Tester to evaluate a new aluminum alloy, subjecting it to 1,000 hours of salt spray followed by high humidity and SO₂ exposure. The data revealed that the alloy retained 90% of its strength, making it a viable alternative to more expensive stainless steel. In the aerospace sector, a component supplier tested titanium fasteners under combined salt spray and UV radiation, discovering that a specific surface treatment reduced corrosion by 60% compared to standard treatments, extending part lifespan.
“The MultiEnv Salt Spray Tester bridges the gap between single-condition testing and real-world complexity,”TOBO GROUP’s Product Manager. “Materials don’t exist in isolation—they face a mix of salt, humidity, chemicals, and radiation. By simulating these combined forces, we’re giving manufacturers the data they need to build truly durable products.”
