For R&D teams pushing material innovation, manufacturing facilities scaling production, or labs adapting to new industry standards, traditional salt spray testers are a rigid constraint—they come with fixed features, no way to add advanced sensors, switch test modes, or expand capacity as needs change, forcing teams to buy new equipment entirely when their testing requirements evolve. An aerospace R&D lab, for example, outgrew its basic tester when it shifted from coating validation to electrochemical corrosion testing; a consumer goods manufacturer needed to add biological compatibility checks but couldn’t upgrade its standard unit. The ModularFlex Corr Salt Spray Tester—launched by TOBO GROUP, a leader in adaptive testing solutions—solves this with a fully modular design that lets users build, upgrade, and reconfigure their system over time. Starting with a core chamber unit, teams can add interchangeable modules for specialized testing (e.g., electrochemical analysis, biological monitoring, high-pressure simulation) or expand capacity (e.g., extra sample racks, larger chambers) without replacing the base system, making it corrosion testing that grows with you—no more settling for one-size-fits-all equipment or wasting budget on redundant tools.
At the heart of ModularFlex Corr is a rugged, ASTM/ISO-compliant core chamber (0.2m³ working volume) that handles standard salt spray testing (3–5% NaCl, 30–50°C) out of the box, with a design that prioritizes compatibility: universal mounting points for modules, a user-friendly touchscreen that integrates seamlessly with added features, and a scalable power supply that supports up to 8 modules simultaneously. The core unit includes basic corrosion monitoring (temperature, humidity, fog density sensors) and can run standalone for standard tests—making it ideal for small labs starting with basic needs. A startup developing corrosion-resistant coatings began with just the core unit, running ASTM B117 tests to validate early prototypes. “We didn’t need advanced features right away,” says their R&D lead. “But knowing we could upgrade later meant we didn’t have to compromise on quality for our budget.”
When teams need to move beyond visual corrosion checks to measure electrochemical properties (e.g., corrosion current density, polarization resistance), the ECA Module (Electrochemical Corrosion Analysis) plugs directly into the core unit. It adds a potentiostat/galvanostat, reference electrodes (Ag/AgCl), and software for cyclic voltammetry and electrochemical impedance spectroscopy (EIS)—turning the basic tester into an advanced material analysis tool. A university materials science lab used this module to study the corrosion behavior of new aluminum-lithium alloys for aircraft: “We started with standard salt spray tests, then added the ECA Module to understand why certain coatings failed,” explains their lead researcher. “The upgrade took 30 minutes, and we didn’t have to learn a new system—everything integrated with the core touchscreen.” The module also includes pre-loaded analysis templates for ASTM G3-89 (standard practice for electrochemical measurements) and ISO 16773-2 (automotive coatings), ensuring compliance with specialized standards.
“Industries don’t stand still—neither should testing equipment,” says TOBO GROUP’s Adaptive Testing Director. “ModularFlex Corr lets teams invest in what they need today, then add what they need tomorrow. It’s not just about saving money—it’s about having a testing system that evolves with your innovation.” The system’s modules are backward and forward compatible, meaning older modules work with new core units (and vice versa), and new modules are released regularly to address emerging industry needs (e.g., AI-driven analysis, carbon-neutral testing).
ModularFlex Corr complies with global standards including ASTM B117, ISO 9227, IEC 60068-2-11, and ISO 10993, ensuring test results are audit-ready and industry-recognized. It also includes cloud connectivity to sync data across modules and track system upgrades—ideal for multi-site facilities or labs managing multiple configurations.
