Advantages
1. Precision Gas Control: Equipped with high-accuracy SO₂ sensors and intelligent PID control, the chamber maintains stable concentrations (±5 ppm), temperature (±0.5 °C), and humidity (±1% RH). This ensures highly repeatable corrosion testing results for metals, coatings, and electronic components.
2. Eco-Friendly Exhaust System: The built-in NaOH neutralization tank and sealed airflow design safely remove toxic SO₂ before release. This combination of efficiency and environmental responsibility protects both users and the surrounding environment.
3. Compact Yet Flexible Design: Adjustable sample shelves accommodate various specimen sizes, while uniform airflow ensures consistent exposure across all samples. The chamber’s efficient layout maximizes workspace usage without sacrificing performance.
4. Accelerated and Reliable Testing: Rapid and uniform exposure to corrosive gas allows months of natural corrosion to be simulated in just days. Programmable multi-step profiles reduce setup time and increase testing throughput, improving R&D and QA efficiency.
5. Durability and Operator Safety: The acid-resistant 316 stainless steel interior and reinforced outer frame ensure long-lasting performance, even under continuous SO₂ exposure. Safety features like double-layer gaskets, emergency locks, and leak-proof design protect both operators and samples.

Operate Guide of the SO2 Noxious Gas Test Chamber
Before starting, ensure the chamber is properly connected to power and the NaOH exhaust system is in place. Set the desired SO₂concentration, temperature, and humidity on the programmable PID touchscreen controller. Load samples evenly on the adjustable shelves, avoiding contact with chamber walls to ensure uniform gas exposure. During testing, monitor real-time readings on the display or via remote access, and follow safety protocols including emergency stop procedures. After the test, allow the chamber to purge residual SO₂ through the neutralization system before opening the door.

FAQs
Q1: How does the SO₂ Noxious Gas Corrosion Test Chamber prevent gas leakage? Does it have alarms?
A1: The chamber uses dual concave-convex sealed doors to ensure airtightness, verified by a 3 kg internal pressure test before shipment. There is no built-in alarm system, but for added safety, it is recommended to place the chamber in a dedicated sealed room if possible.
Q2: How is complete exhaust of SO₂ gas ensured?
A2: A built-in SO₂ sensor continuously monitors residual gas. The exhaust process typically takes around 30 minutes, allowing thorough discharge while the 10% NaOH tank neutralizes the gas for safe handling.
Q3: Could any SO₂ gas remain after exhaust?
A3: Residual gas is minimized by the sensor-monitored exhaust and NaOH absorption system, ensuring concentrations remain well below the EU safety limit of 50 PPM.
