See What Your Gas Detection Has Been Missing

The all new Honeywell Searchline Excel™ Plus and Searchline Excel™ Edge

Our Most Powerful Optics for Advanced Open Path Flammable Gas Detection

Upgrade Your Protection with Honeywell.

Flammable hydrocarbon gas leaks are a threat to workers, assets and the environment across multiple industries. If these leaks are not detected, they could result in litigation and fines or escalate into devastating fires and explosions.

Open path gas detectors create an invisible line that senses the presence of flammable hydrocarbon gas passing in between the Transmitter and Receiver pair. The Searchline Excel™ Plus monitors short and mid-range applications from 2 to 120 meters (6 to 393 ft) while the Searchline Excel™ Edge monitors long range perimeter monitoring applications from 60 to 330 meters (196 to 1083 ft)

A layered system that integrates a variety of gas and flame detection technologies ensures optimal protection against flammable gas risks and help achieve total site protection.  Searchline Excel Plus or Edge open path flammable gas detectors add a critical layer in your fixed gas detection system.
