Introduction
This range of ruggedised, intrinsically safe and
weatherproof sounders, intended for use in
potentially explosive atmospheres, has been
designed with high ingress protection to cope
with the harsh environmental conditions found
offshore and onshore in the oil, gas and
petrochemical industries.
The unit is available in 12V and 24V versions
and for gas groups IIB or IIC.
A lower cost, uncertified version is available for
use in non-explosive atmospheres.
