Q-LAB Q-FOG CRH Cyclic Corrosion Tester

Q-LAB Q-FOG CRH Cyclic Corrosion Tester

In modern corrosion testing standards—especially within the automotive, aerospace, and high-tech surface coating industries—traditional salt spray chambers are no longer sufficient. The Q-LAB Q-FOG CRH cyclic corrosion tester represents a technological breakthrough, delivering active relative humidity control to perfectly satisfy the world’s most complex and stringent corrosion test requirements today.

The Q-LAB Q-FOG CRH is engineered to exceed rigorous testing standards set by major automotive corporations such as ISO, ASTM, SAE, as well as proprietary standards from Ford, GM, Volvo, Chrysler, and Volkswagen.

Outstanding Differences of the Q-FOG CRH Series

While the SSP series performs basic salt spray and the CCT series offers moderate humidity control, the Q-FOG CRH (Controlled Relative Humidity) series stands as the most comprehensive system thanks to the integration of:

• Active Relative Humidity Control System (RH Control): The chamber is capable of adjusting, controlling, and precisely maintaining relative humidity levels from very low up to 95% or more, utilizing an air pre-conditioner fine-mist system and an intelligent heating system.
• Shower Function: In addition to conventional salt spray fogging, the CRH series incorporates an overhead shower spray system. Water or solution sprays directly and uniformly onto the specimen surfaces in strict accordance with demanding automotive standards (such as ISO 16701 or Volvo STD 423-0014).

Technical Features & Outstanding Benefits

• 100% Automated Multi-Cycle Transition: Operators can program the chamber to automatically and smoothly transition between different environments: Salt Spray → Shower → Forced Air Dry-Off → Condensing Humidity → Controlled Relative Humidity (RH) without any manual intervention.
• Advanced Ceramic Spray Nozzle: Ensures absolutely uniform salt fog distribution throughout the chamber and prevents nozzle clogging, delivering highly repeatable test results.
• Durable Composite Material: The internal chamber is molded from premium fiber-reinforced plastic (FRP), which not only resists corrosion from high-concentration salt and acids but also provides exceptional thermal insulation to save energy.
• Intuitive Touchscreen Interface: The control screen displays comprehensive temperature and humidity parameters via real-time graphs. The system supports multi-language operation and data logging via a USB port for effortless inspection report exporting.
