The Gas-Pro IR is an important addition to the Gas-Pro range and it is best suited for the oil and gas industry. The Infrared sensor can detect methane, pentane or propane using infrared (IR) sensor technology. The Gas-Pro IR is ideal for detecting potentially explosive gases where traditional, ”pellistor”, catalytic sensors will fail - especially in places of low oxygen surroundings.

The infrared measurement gives improved reliability and has the advantage of little chance of being poisoned; the Gas-Pro IR is inherently safer and saves the need of regular and expensive pellistor replacement when used in likely contaminated environments.

IR sensors are reliable in some environments that can cause pellistor-based sensors to function incorrectly or in some cases fail:

• In some industrial environments, pellistors are at risk of being poisoned or inhibited. This leaves worker on their shift unprotected. IR sensors are not susceptible so significantly enhance safety in these conditions.
• Exposure to high levels of flammable gas can cause “sooting” of pellistors, reducing their sensitivity and potentially leading to failure Pellistors require oxygen to function. However, IR sensors can be relied on in applications such as fuel storage tanks where there is little or no oxygen, due to flushing with inert gas prior to maintenance or which still contain high levels of fuel vapours.
• The fail-safe nature of IR sensors, which automatically alert you to any fault, provides an additional layer of safety.

Gas-Pro IR measures in %LEL and has been certified for use in hazardous areas as defined by both ATEX/IECEx and UL.
