Reliable Corrosive Gas Testing for IEC 60068-2-42 & IEC 60068-2-60 Compliance
LIB industry noxious gas test chamber enables manufacturers to identify corrosion risks early by accurately simulating real-world exposure to temperature, humidity and trace corrosive gases.
Low-level gases such as SO₂, H₂S and NO₂ can cause long-term damage to metals, coatings and electronic components, often leading to unexpected failures in service.
By providing precise control of gas concentration, temperature and humidity, the system supports IEC 60068-2-42 and IEC 60068-2-60 compliant single and mixed gas testing, delivering repeatable and trustworthy corrosion evaluation results.
Flexible reach-in, walk-in and customized configurations ensure the solution adapts to your specific testing requirements.

Noxious Gas Test Chamber Working Principle
Test samples are placed inside the sealed test chamber
Corrosive gas (single or mixed) is precisely injected via high-accuracy flow control
Uniform gas distribution is achieved through centrifugal air circulation
Temperature, humidity and gas concentration are continuously monitored
After testing, exhaust gas is purified and safely discharged
Operators can observe sample changes in real time through the inspection window.
Product Design Details of Noxious Gas Test Chamber
High-Sealing Chamber Structure
Independent Gas Delivery
Multi-layer sealing design with corrosion-resistant materials effectively prevents toxic gas leakage, while an electromagnetic safety door lock prevents accidental opening during operation, ensuring operator safety and stable gas concentration throughout long-duration testing.
Each gas is supplied through an independent pipeline controlled by high-precision mass flow controllers, eliminating cross-contamination and guaranteeing accurate mixed gas ratios.
Real-Time Gas Concentration Monitoring
Corrosion-Resistant Workroom
Integrated H₂S, SO₂, NO₂ and Cl₂ sensors continuously monitor gas concentration and provide closed-loop feedback control to maintain stable test conditions.
The noxious gas chamber interior is constructed from SUS316 stainless steel, providing excellent resistance to aggressive corrosive environments and long service life.
Exhaust Gas Treatment
Smart Control & Easy Maintenance
The exhaust gas is neutralized using an NaOH solution, with a built-in spray system inside the solution tank to enhance gas–liquid contact and accelerate exhaust gas treatment, ensuring safe and efficient discharge after testing.
Programmable color LCD touch screen controller with Ethernet and PC connection allows intuitive operation, remote monitoring and simplified maintenance.
