The LGD F200 series is based on a contactless, near-infrared absorption measurement 

of the target gas. The systems are self-contained, ready-to-use OEM modules, using a 

flowthrough cell set-up for extractive measurements. The slightly bigger LGD F200 (H) 

version features optional cell heating up to 220°C for hot gas measurements in process 

control and environmental compliance related applications.

The system has micro-processor-driven readout electronics and digital and/or analog data 

outputs for industry-standard connectivity. Proprietary electronic lock-in technology allows 

separating gas absorption information from electro-optical system information, eliminating 

the need for a physical reference channel and providing continuous sensor status monitoring.
