Introduction to PhoCheck TIGER
PhoCheck TIGER is a portable gas detector that uses Photo-ionization technology to detect a
large range of Volatile Organic Compounds (VOC's) 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 & Safety mode 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 STEL's and TWA's
are continually calculated and compared to level
s set in the instrument‟s gas table.
The TIGER can be upgraded from the users own desk top. Additional features can be added
without the need to return the instrument to a service centre.
Like it's predecessor, P, the TIGER also has an intuitive graphical interface allowing
easy access to instrument settings. Two soft keys 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.
TIGER PC (the TIGER's PC Software) maintains the intuitive look and feel by adopting the
same graphical symbols. TIGER PC also helps manage logged data files and multiple
instrument settings in a clear and concise way.
The TIGER uses a Lithium-ion battery that not only boasts an impressive running time and short
charge time, but also allows battery packs to be replaced in potentially hazardous environments.
Field replaceable alkaline battery packs are also available for when power to charge is
unavailable.
The TIGER has true USB capability so the instrument can be connected directly to a PC via a
standard USB cable. It also offers fast data download.
A loud audio output, vibration and bright LED's indicate alarm conditions. Orange and Red
LED's indicate High and Low conditions respectively. This colour scheme is used within TIGER
PC to offer clear indication of alarm levels within logged data.
