TIGER Select handheld benzene detector – now with ION Science benzene pre-filter tube!  

Benzene & Total Aromatic Compound (TAC) detection in one instrument

The Tiger Select is a revolutionary hand-held gas detector for the rapid, accurate detection of benzene and Total Aromatic Compounds (TACs).

Utilising the high output Ion Science 10.0 eV detection system, a reading for TACs is seen immediately on start-up. Should aromatics be detected, an ION Science benzene pre-filter tube can be easily attached to ensure fast detection and selective measurement of benzene.

Throughout the measurement process, Tiger Select continues to display real-time data, ensuring the final reading represents the full value of actual benzene present. Benzene concentrations are displayed down to parts-per-billion (ppb) levels, giving you accurate, reliable data you can count on.

Tiger Select is capable of providing 15-minute short-term exposure limits (STELs) and 8-hour time-weighted averages (TWAs) for total aromatic compounds (TACs). A 10.6 eV lamp can easily be installed for the detection of a wide range of VOCs.

In addition, the unique Ion Science PID sensor incorporates both humidity resistant technology and anti-contamination design for extended operation in difficult working environments.

The Tiger Select benzene and total aromatic compound detector can also be used in standard Tiger operational mode without the use of a benzene pre-filter tube to deliver active indications of volatile organic compounds (VOCs), including benzene, at concentrations as low as 1 ppb benzene equivalent.
