ION Science Tiger Select

Benzene & Total Aromatic Compounds in one Instrument

The revolutionary Tiger Select; two-mode operation for rapid benzene and Total Aromatic Compounds providing accurate, reliable data you can count on.

A revolutionary hand-held detector, Tiger Select has two basic modes of operation capable of detecting TACs without the tube attachment, or benzene with the benzene pre-filter tube. Utilizing the high output Ion Science 10.0 eV detection system, a reading for Total Aromatic Compounds (TACs) is seen immediately on start-up. Should aromatics be detected, a benzene pre-filter tube can be easily attached to ensure rapid detection and selective measurement of benzene. The unit can also provide 15 minute STEL and 8 hour TWAs for TACs.

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 ppb levels, giving you the most accurate, reliable data you can count on.

In addition, the unique MiniPID VOC sensor incorporates both Anit-contamination technology and Fence Electrode technology for extended operation in difficult working environments.

Tiger Select can also be used in standard Tiger operational mode, without the use of a benzene pre-filter tube, to deliver active indications of VOCs including benzene at concentrations as low as 1 ppb benzene equivalent. For more information see the PhoCheck Tiger Brochure.
