2. Product Overview
The TIGER is a portable gas detector that uses photo-ionization technology to detect a large range of
Volatile Organic Compounds (VOCs) which can be dangerous from both a poisoning and explosive
perspective.
The TIGER uses a Photo-Ionization Detector (PID) to measure gas concentrations. The patented
fence electrode technology minimises the effects of moisture and contamination, avoiding the need
for compensation.
Survey is the default mode of operation. This mode is often used in applications such as Head Space
Sampling and Leak Detection where several areas (or Zones) are to be monitored and readings data
logged. All sensor readings are real time measurements and alarm levels are set manually.
Health and Safety mode (optional) is used to check for conformity of short-term exposure levels
(STEL) or time- weighted averages (TWA) that are specific for particular hazardous environments (for
example EH40 in the UK and OSHA in the USA). In this mode of operation STELs and TWAs are
continually calculated and compared to levels set in the instrument’s gas table.
The TIGER has an intuitive graphical interface allowing easy access to instrument settings. Two keys
A and B can be configured to suit the user’s application, so many functions can be
selected without entering the main menu structure. This improves efficiency of use, particularly with
repeatable tasks.
