INFRARED
PIRDUCT IR Gas Monitor
The Model PIRDUCT DuctWatch (Spec Sheet: 90-1188) is an infrared (IR) based flammable gas
detection/monitoring solution ideal for combustion turbine enclosure detection/monitoring and
sample air handling ductwork applications. The DuctWatch is easy to install and commission,
and does not require expensive extractive sampling system hardware. Providing a full scale
measurement range of 0 to 15% LFL (7500 ppm) methane vapor concentration, the DuctWatch
delivers a new level of flammable hydrocarbon gas protection for high airflow environments.
PIRDUCT is compatible for mounting on any flat mounting surface, and is provided with a solid
mounting plate with seal gasket to prevent air leakage. Minimum internal duct width of 3 feet
(1 meter) is required for proper instrument clearance and installation. Air movement is required
for proper device performance.
