摘要:
Chemical indicators for acidic or basic gases include an inert, porous substrate, an indicator dye or mixture of dyes contained within at least some of the pores of the inert, porous substrate, and an inert adhesive layer attached to the inert, porous substrate. The porous substrate may be a microporous substrate.
