Introduction to P_
________________________________________
P is a portable gas detector, suitable for the detection of a large range of Volatile Organic
Compounds (VOC's), which are dangerous from both a poisoning and explosive perspective. Total VOC‟s are
detected using PID (Photo Ionisation Detection) technology.
The P versions are fully upgradeable in the field (i.e. P 1000 to a 5000 or a 2000 to a
3000 etc). See page 37 for more details relating to upgrade options.
P has two principle modes of operation; Survey and Health & Safety. Health & Safety mode is
available on 3000 and 5000 versions.
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
levels set in the instrument‟s gas table. For more information on these modes of operation please see page
19.
P
versions 2000, 3000 and 5000 automatically data log the readings every second. These readings
are stored in the instrument's memory with a date and time stamp. For more information please see page
18.
