Caroline FYL

24/7 monitoring system


Caroline FYL is the first combined system based on a camera and a laser for methane detection and quantification. This upgrade version of Caroline FY combines OGI detection capabilities with punctual quantification features in the most advanced monitoring system available.

Caroline fixed series integrate the latest technology in uncooled infrared detectors, offering consistent and error-free performance. It is the most complete system for constant monitoring of environments with risks of CH4, SO2, VOC’s, Natural Gas and/or hydrocarbons leaks.
