Salt Spray Test Chambers: Meet Global Standards for Material Corrosion Resistance

Shanghai – TOBO GROUP, a leader in industrial-grade testing durability, is proud to launch the Duraguard Pro Salt Spray Tester—a rugged, low-maintenance system engineered to minimize downtime and deliver consistent performance for years, addressing the critical pain point of frequent maintenance interruptions in high-volume industrial settings. Unlike conventional salt spray testers that require weekly part replacements (e.g., clogged nozzles, corroded chambers) and annual overhauls, this platform integrates self-preserving components and durable materials to support 24/7 uninterrupted testing—essential for industries like automotive manufacturing, heavy machinery, and large-scale hardware production, where paused testing can delay production lines or disrupt quality control (QC) workflows.
At the core of the Duraguard Pro is its Self-Sustaining Maintenance Design, which eliminates the need for constant manual upkeep. The system features a dual-stage self-cleaning fog generator: a pre-filter traps debris before it reaches the nozzle, and a built-in ultrasonic cleaner removes salt buildup from the nozzle every 12 hours—cutting nozzle replacement frequency from once per week to once every 6 months. Key wear parts, such as chamber gaskets and solution filters, are made from chemical-resistant fluoroelastomer and reinforced polypropylene, designed to last 3x longer than standard components; they also use a tool-less snap-fit design, letting technicians replace them in 5 minutes without specialized equipment. A large automotive assembly plant using the Duraguard Pro reported that maintenance time for corrosion testing dropped from 8 hours per week to 1 hour, freeing up QC teams to focus on other tasks and reducing downtime-related delays by 40%.
Complementing its low-maintenance design is the system’s High-Lifespan Structural Build, engineered to withstand the rigors of industrial use. The test chamber and chassis are constructed from duplex stainless steel (2205 grade)—a material with 2x the corrosion resistance of standard 316L stainless steel and superior impact strength, ensuring the unit remains intact even in busy factory environments where accidental bumps are common. Critical internal components, such as the temperature sensor and solution pump, are coated in a ceramic-titanium alloy that resists degradation from long-term salt exposure; lab tests show these components maintain accuracy for up to 8 years, compared to 3-4 years for standard parts. A heavy machinery manufacturer noted that their Duraguard Pro operated continuously for 5 years without major repairs, while their previous tester required a full chamber replacement after 2.5 years—saving them $25,000 in replacement costs.
The Duraguard Pro further supports uninterrupted testing with its Redundant Backup System, which prevents unexpected shutdowns. It includes a secondary fog generator and backup power supply that activate automatically if the primary system fails; for example, if the main pump malfunctions mid-test, the backup kicks in within 10 seconds, ensuring no data loss or test interruption. The system also has a large 40-liter salt solution tank (twice the size of standard tanks) that reduces the frequency of refills from once per day to once every 3 days—ideal for overnight or weekend testing when staff are not on-site. A hardware manufacturer using the Duraguard Pro to test 1,000+ door hinges per week relied on the backup system during a power fluctuation: the unit switched to backup power seamlessly, and the large tank ensured testing continued until staff arrived to address the issue—avoiding a 2-day delay in hinge production.
Real-world applications across industrial sectors underscore the system’s value: An automotive OEM used the Duraguard Pro to test corrosion resistance of steel chassis components, running 24/7 tests for 6 months straight with only monthly quick checks—meeting their tight production timeline for a new vehicle model. A heavy equipment maker validated aluminum hydraulic parts, leveraging the system’s durable build to handle daily use by multiple shift teams without performance drops. A hardware supplier testing stainless steel fasteners for construction projects used the large solution tank and self-cleaning nozzle to run weekend tests unattended, cutting their time-to-market for a new fastener line by 2 weeks.
“Duraguard Pro was built for the realities of industrial testing—where downtime isn’t just inconvenient, it’s costly,” said TOBO GROUP’s Industrial Solutions Director. “Manufacturers don’t need a tester that demands constant attention; they need one that works as hard as their teams do. This system delivers that reliability, letting them keep testing on track and production moving forward.”
