PIRDUCT IR Gas Monitor
The Model PIRDUCT DuctWatch™ (Spec Sheet: 90-1188) is an infrared (IR) based flammable gas
monitoring solution designed for combustion turbine enclosure monitoring and similar 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.
