DuctWatch IR Gas Detector (PIRDUCT)
The Model PIRDUCT DuctWatch is an infrared (IR) based flammable gas detection solution, designed for combustion turbine enclosure monitoring and similar air handling ductwork applications. The PIRDUCT 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 (0 to 7500 ppm) methane vapor concentration, the PIRDUCT delivers a new level of flammable hydrocarbon gas protection for high airflow environments.

The Technology Behind the Precision: The PIRDUCT Probe
The heart of the DuctWatch IR Gas Detector is its unique PIRDUCT optical probe. Inserted through the duct wall, it spans the interior, allowing moving air to pass directly through the detection chamber. This smart design is, in essence, an IR beam detector optimized for the instant analysis of hydrocarbon vapors. Furthermore, the PIRDUCT is six times more sensitive to combustible gas than a conventional IR point detector, improving detection in applications where air stratification can occur.
Why Choose the DuctWatch?
Rapid In-Duct Response
With the PIRDUCT optical probe inserted directly into the airflow, the DuctWatch analyzes gas concentration in real-time, ensuring a significantly faster response time than traditional point detectors.
Simplified Installation & Perfect Retrofit
Delivered as a pre-aligned, ready-to-install package, the DuctWatch IR Gas Detector is the ideal solution for modernizing existing systems, allowing for the replacement of point detectors with minimal effort and expense.
Eliminates Expensive Sampling Systems
Forget the complexity and high costs of extractive sampling hardware. The DuctWatch performs in-situ measurement, reducing installation costs, maintenance, and potential points of failure.
Reliability with Continuous Self-Testing
The system performs a continuous self-test that automatically indicates a fault or a fouled optics condition, ensuring the detector is always operational and your facility is safe.
