Advantages
1. Advanced Ozone Simulation: The chamber accurately replicates ozone exposure conditions with concentrations from 1–1000 PPHM, temperature control from 0–100 °C, and humidity from 30–98 % RH. This precise environment ensures reliable assessment of elastomer aging, cracks, and material degradation under accelerated ozone stress.
2. Dynamic and Static Sample Versatility: Equipped with both static and rotating holders, the chamber can stretch samples 5–80 % and rotate 0–10 r/min. This dual-mode design simulates real-world mechanical stress for gaskets, cables, and seals, providing comprehensive performance data for development and quality assurance.
3. Durable, Corrosion-Resistant Construction: The SUS304 stainless steel interior resists ozone-induced corrosion, while the coated exterior ensures industrial-strength durability. Combined with robust airflow and cooling systems, the chamber maintains long-term stability even under continuous testing cycles.
4. Intelligent Control and Monitoring: A programmable PID touchscreen controller allows precise regulation of ozone, temperature, and humidity. Real-time data logging, Ethernet connectivity, and embedded sensors guarantee accurate, reproducible results while simplifying remote monitoring and test management.
5. Safe and Eco-Friendly Operation: The integrated activated carbon exhaust system neutralizes residual ozone before release, ensuring operator safety and compliance with environmental regulations. Efficient airflow and low-noise design reduce energy consumption while maintaining optimal test conditions.

Operate Guide of the Ozone Test Chamber
Before starting the ozone resistance test, ensure the chamber is properly connected to power and all safety interlocks are engaged. Load samples onto the static or dynamic holders according to the test requirements, and close the chamber door securely. Set the desired ozone concentration, temperature, and humidity using the PID touchscreen controller, and program the test duration and any dynamic rotation or stretching cycles. During the test, monitor real-time parameters on the display or remotely via Ethernet/PC connection. After completion, allow the chamber to purge ozone through the exhaust system before opening the door, and carefully remove the samples for analysis. Regular maintenance of filters, sensors, and the ozone generator is recommended to ensure consistent performance.

FAQs
Q1: What is the maximum stretching capacity of the sample rack in the ozone test chamber?
A1: The sample rack can stretch rubber or similar specimens from 5% to 50%, adjustable according to testing requirements. Both static and dynamic configurations are available to meet different aging test needs.
Q2: What is the stretching speed of the sample shelves?
A2: The stretching speed is adjustable between 1 cm/min and 10 cm/min. Standard ozone tests usually use slower speeds to ensure stable conditions and accurate results.
Q3: How is ozone fully removed before being released into the air?
A3: Ozone is neutralized using activated carbon adsorption. Proper carbon volume and weight are pre-calculated (e.g., 2.5 kg per 1000 L of gas), and annual replacement is recommended to maintain effective purification.
