Overview

The Honeywell 2104B2081 Open Path Infrared Gas Detector, also known as the Searchline Excel, is a proven solution for detecting flammable gases in hazardous industrial environments. It operates by transmitting an infrared beam between a transmitter and receiver, with gas detection achieved through absorption in the beam path. The detector is designed to be unaffected by sunlight, fog, or harsh weather, making it suitable for deployment in extreme conditions, from Arctic cold to desert heat.

With more than 6,000 units installed worldwide, the Searchline Excel is recognized as the industry’s most trusted open-path gas detection system. The 2104B2081 model is certified for hazardous area use and supports ATEX compliance, ensuring safety in petrochemical, refining, and offshore applications.
