Product Overview
GASES THAT ARE CROSS SENSITIVE TO BENZENE WILL RESULT IN SIGNIFICANT
ERRORS IN READING.
The TIGER Select is a 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. Benzene Pre-
filter Tubes absorb many VOC gases, but benzene will pass through.

The number of gases a PID can detect directly relates to the maximum photon energy (eV) of the PID
Lamp being used. As TIGER Select uses a 10.0 eV light source, many gases associated with benzene
are ignored due to their higher eV.
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.
The 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). In addition, the ION Science
MiniPID 2 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
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.
The TIGER Select has been designed and certified Intrinsically Safe.
