ATEX laser methane detector
November 1st 2008 Crowcon Detection Instruments
has extended its agreement with
the technology development arm of
a major Japanese gas utility to offer
the new LaserMethane mini
methane leak detector.
The LaserMethane mini (LMm) is
lightweight, compact and capable
of detecting ppm levels of methane
from a distance of up to 100m.
Handheld, the LMm weighs only
600g and measures W70 x H179 x
D42mm. With advances including
automatic ranging, colour LCD, five
hour battery, extended temperature
range and IP54, the unit
complements the previously
launched LaserMethane Detector
(LMD) and utilises the next
generation of Tuneable Diode Laser
Absorption Spectroscopy (TDLAS).
ATEX approval allows the unit to
be used in Zone 1 areas for onplant
use, as well as detecting
escapes in hard to reach or
inaccessible areas such as roof
spaces, pipes crossing rivers or
roads, and fenced enclosures. This
negates the need for personnel to
put themselves at risk by entering
suspected escape areas.
The LMm performs a self check
on start-up and verifies the
operation and calibration of the
laser diode by referencing an inbuilt
methane cell. More articles from Crowcon Detection Instruments Ltd: |
