LASER GAS DETECTION axetris@axetris.com www.axetris.com axetris Company of the Leister Group MICRO-OPTICS INFRARED SOURCES Axetris is offering Laser Gas Detection (LGD) modules with exceptional advantages and value for the customer. Tunable Diode Laser Spectrometry (TDLS), enhanced by proprietary technology, is used for the measurement of CO2, NH3, CH4, HCl, (H2O). The modules are designed for integration by Original Equipment Manufacturers (OEMs), active in the field of gas detection and monitoring in diverse industries. 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. Low maintenance operation and long life time provide customers with exceptionally low cost-of-ownership and make the LGD F200 the ideal instrument for your OEM applications Main applications • Process control: SCR, incineration & combustion processes, ... • Emission monitoring: Power generation, engine development, waste incineration furnaces, ... • Environmental monitoring: Landfill & green-house gases, livestock, ...
