1. Product introduction

TWA-300T low-flow air sampler is not only suitable for sampling of various absorption tubes, but also an ideal instrument for solid adsorption tubes. It has been more and more widely used for monitoring and evaluation of occupational and environmental hygiene.
Solid adsorption tubes (including activated carbon tubes and silicone tubes, etc.) can be used for long-term sampling and short-term sampling, either for fixed-point sampling or for individual sampling. Collect various inorganic gases and vapors; it can be used for both the monitoring package of the maximum allowable concentration ( MAC ) of sanitary standards and the monitoring package of time weighted average concentration ( TWA ).
