Safety engineers have long been aware that monitoring airflow in ductwork gives them the ability to boost protection of confined spaces in challenging industrial applications. The DuctWatch IR gas detector from Det-Tronics provides a capable solution.
The PIRDUCT optical probe is inserted through the duct wall and spans across the duct interior, allowing moving air to pass into the detection chamber for analysis of hydrocarbon vapor concentration. It is well suited for retrofit replacement of point detectors and is, in essence, an IR beam detector delivered in a pre-aligned, ready to install package.
Additionally, the PIRDUCT is six times more sensitive to combustible gas than a conventional IR point detector and improves detection in applications where air stratification can occur.
