Portable Benzene Gas Detector: Tiger Select

The Tiger Select is a portable benzene gas detector with two modes of operation for the high-speed detection of benzene and Total Aromatic Compounds (TACs), which delivers accurate, reliable data.

Tiger Select portable benzene gas detector is able to offer 8-hour time-weighted averages (TWAs) and 15 minute short-term exposure limits (STELs) for total aromatic compounds (TACs).


The Tiger Select portable benzene gas detector provides real-time data, ensuring the final reading depicts the total value of benzene present. Benzene concentrations are shown down to parts-per-billion (ppb) levels, providing the user with accurate, reliable data that they can trust.

Tiger Select can also be utilized in ‘standard Tiger operational mode‘ without the need for a benzene pre-filter tube to supply active signs of volatile organic compounds (VOCs), including benzene, at extremely low concentrations - around 1 ppb benzene equivalent.

The Tiger range has three gas detection instruments in total; the other two include Tiger and Tiger LT.
