Product details
Mixed Gas Corrosion Chamber
Workroom
The inner chamber is constructed from 316 stainless steel, providing excellent resistance to corrosion caused by multiple gases.
The height of sample shelves is adjustable and can be removed directly to facilitate the various sizes of test samples.
Four Mixed Noxious Gas Flowmeters
High-precision mass flow controllers regulate the input of each noxious gas with fine control and excellent repeatability.
Four Mixed Noxious Gas Cylinders
High-purity gas cylinders for connecting various corrosive gases. The gas mixing system can precisely control the proportion of various gases according to the test requirements.
Noxious Gas Exhaust Device
Ensures operator safety and environmental protection by neutralizing noxious emissions before release.
LIB mixed gas corrosion chamber has a number of safety protection, while supporting personalized configuration, suitable for electronics, automotive, aerospace, coatings and other industries. Contact LIB for configuration solutions, control system upgrades, and detailed technical specifications.
