Portable Toxic Vapor Collector

SeaPort 4TD


Seacoast Science’s SeaPort 4TD provides a tool for environmental monitoring for noxious and toxic vapors to help protect workers and the general public.

The SeaPort-4TD is designed specifically for sampling using up to four conventional thermal desorption (TD) air-sampling tubes. Its flexible design allows for individually addressable sorbent tubes for short or long-term air monitoring using commercial, off the shelf (COTS) TD tubes. A simple but flexible user-interface allows the user to preprogram start, stop and flow profiles for each sorbent tube individually.
