GSA room air measuring devices detect solvents

Solvent indoor air measuring-devices

GSA SG350ex, SG5200 and SG5100ex room air measuring devices for sampling solvents

GSA indoor air measuring devices reliably detect the presence and harmful quantities of solvents in the home. If, for example, an unpleasant odor develops in the course of new furniture or other furnishings, or if symptoms only occur in one room, there may be solvent pollution.


The GSA measuring device SG350ex is particularly suitable when it comes to escaping gases. These room air measuring devices therefore provide more information about the gases present in the room under investigation.
