It belongs to the category of new material testing and measurement equipment and can be used in scenarios requiring activated carbon testing, such as activated carbon product production, government supervision of activated carbon adsorption performance, and self-inspection of activated carbon adsorption processes for organic waste gas. It is particularly suitable for industries that use activated carbon adsorption to treat volatile organic compounds (VOCs).
