Salt Spray Corrosion Test Chamber TTSS Series
Salt Spray Corrosion Test Chamber is different from the basic salt spray test chamber. Cyclic corrosion test chamber exposes samples to a series of different environments in repetitive cycles that incorporate temperature, humidity, salt spray and dry.
Chamber material
- Material Thickness: Models below 90 feature a 5mm thickness, while models above 90 use 8mm imported gray-white impact-resistant PVC board. These materials offer high-temperature resistance up to 85°C and are highly corrosion-resistant.
- Support Frame: Constructed with a ￠10mm glass fiber rod that resists corrosion. The V-shaped plastic steel frame and fiber rod are angled to keep the test object positioned at a 15–30 degree incline.
- Pressure Barrel: Crafted with a seamless weld using 2.0mm SUS304 stainless steel plate, ensuring durability and reliability.
- Heating System: Equipped with a titanium alloy electric heating tube, designed for exceptional corrosion resistance and longevity—lasting 3–5 years longer than standard stainless steel heating tubes.
- Transparent Cover: Made with 5mm imported German YLIS acrylic sheet, offering meticulous craftsmanship, an attractive appearance, and excellent transparency.
- Water-Gas Separation Design: Features a specialized structure to maintain experimental temperatures effectively. This reduces the need for frequent water replenishment in the pressure tank caused by brine concentration loss and prevents tank leakage.
Touch screen control system (Optional)
Equipped with a 7-inch touch controller, this system supports both constant-value experiments (continuous or steady temperature) and programmable salt spray experiments (intermittent or cyclic). Its versatile design offers multiple functions to meet diverse experimental requirements.
Key Features:
- High-Precision Temperature Control: Includes a PID automatic calculation module and a high-stability platinum temperature probe with an accuracy of ±0.3°C.
- Timing Mode: Offers hour-based timing options for flexible operation.
- User-Friendly Interface: All controls are conveniently placed on a single panel for ease of use and a clear overview.
- Data Storage and Analysis: Accurately stores temperature data during experiments, ensuring intuitive and precise analysis.
This advanced controller simplifies operations while maintaining exceptional accuracy and reliability, catering to various salt spray testing needs.
Water filling system
This system features both automatic and manual water filling capabilities, ensuring uninterrupted experiments even when the water level is low.
Key Features:
- Dual Functionality: Offers the flexibility of automatic or manual water replenishment.
- Continuous Operation: Keeps experiments running smoothly without interruptions.
- Easy Integration: The automatic water replenishment function requires only a connection to a tap water pipe.
- Adaptable Design: Designed to meet diverse environmental requirements.
This system provides a reliable and efficient solution for maintaining optimal water levels during experiments.
Heating Method
The salt spray experiment utilizes direct steam heating, offering several key advantages:
- Rapid Heating: Ensures a quick temperature rise, minimizing preparation time.
- Uniform Temperature Distribution: Maintains consistent conditions throughout the experiment.
- Reduced Standby Time: Enhances efficiency by shortening waiting periods.
This method ensures reliable performance and optimal conditions for salt spray testing.
Control method
This system features a rocker-type standard operation design, combined with advanced functionalities for improved efficiency and user convenience:
- Comprehensive Fault Detection: Includes an early warning system that alerts users immediately in case of a fault.
- Manual Demist Function: Enables the removal of accumulated salt mist during experiments, ensuring clear visibility of the test environment and placement of the product.
- Spray Mode: Operates in continuous spray mode for consistent performance.
These features ensure smooth operation, enhanced safety, and optimal experimental conditions.
Protection devices
This system is equipped with robust safety features to ensure uninterrupted and damage-free operation:
- Double Over-Temperature Protection: Uses Italy EGO technology to automatically cut off heating power if the temperature control meter or heating system fails, preventing high-temperature damage.
- Double Low Water Level Protection: Safeguards against dry burning and damage to heating pipes and pressure barrels by monitoring water levels.
- Overload and Short Circuit Protection: Protects the instrument and its electronic control components from damage caused by electrical abnormalities.
- Low Salt Level Reminder: Alerts users when the brine in the experiment's real brine bucket is running low, avoiding disruptions or abnormalities during testing.
These advanced safety measures ensure reliability and longevity while maintaining optimal experimental conditions.
Measuring cylinder
A built-in fog collection tube is used. Compared with the traditional external type, it is less likely to be damaged.
Spay nozzle
- Quartz Glass Nozzle: Ensures no crystallization even after 4000 hours of use, maintaining consistent spray quality.
- Conical Diffuser: Equipped with a conical diffuser that guides the fog and adjusts the spray amount, ensuring even distribution of the mist.
Sealing method
The inner and outer chambers are connected with sealing grooves and sealed with water, effectively preventing salt mist from leaking out during the experiment. This design ensures a controlled environment and minimizes the risk of contamination or interference.
