AVACO DGTkex gas detector is designed for
detecting combustible gases and organic
vapours. It is certified for use in Zone 1, 21, 2
and 22 areas.

Easy to read display provides on-site information
about gas concentration. Flameproof enclosure
is suitable for demanding conditions.
The catalytic sensor has fast response,
extremely wide range of detectable gases, and
significantly better poison resistance than
traditional type pellistors.
C3H8
NDIR (Non Dispersive Infrared) sensor is more
selective, resistant to chemical attack by most
weak acids, solvents, bases and corrosive
gases (e.g. silicone, tetraethyl lead and sulphur
compounds) and it works in oxygen free
environments.
