ATEX TVOC monitor
November 1st 2009 New from Ion Science is the ATEX
approved 3 wire TVOC (total
volatile organic compound)
monitor, for use without safety
barriers in Zone 2 hazardous areas.
Since the TVOC can be installed
without barriers in a Zone 2 area, it
can be used to directly replace an
existing photoionisation detector
(PID – saving time and costs on
installation.
It is also
available as
an IECEx
and ATEX
approved 4
wire option
for zone 1
areas with
safety
barriers.
Designed for
fixed, continuous
area monitoring, TVOC provides
rapid, accurate detection of volatile
organic compounds (VOCs). The 4-
20mA analogue output allows
TVOC to be integrated into a DCS
control system to give warning or
control of high VOC levels within
the working environment. More articles from ION Science Ltd: |
