LGT-100 Laser Gas Analyzer LGT-100 is a flameproof tunable laser gas analyzer for industrial online analysis and environmental on-line monitoring, which can in-situ analyze O 2, CO, NH 3, CO 2, CH 4, H 2O, HCl, HF and other gases in various complex conditions. It consists of transmitter, receiver and connection box. The transmitter drives the tunable diode to emit laser of certain wavelengths, which passes through the environment to be measured, then reaches the receiver. The receiver performs photoelectricity conversion, signal processing and spectrum data analysis to obtain the measuring result. The connection box contains I/O interface, making the connection of power cable and signal cable convenient. System Composition Light path adjustment seat Light path adjustment seat Receiver Process pipeline Globe valve Protective gas inlet Protective Globe valve gas inlet optical path adjusting, XY direction non-coupling adjusting. drift, long maintenance period, drift ≤ ±1%F.S./half year. "Single line" spectrum technology, free from interference of background gas. Integrated structure design, high stability and reliability. Integrated flameproof structure, consuming less purge gas compared with positive-pressure mode. In-situ measurement without pretreatment system avoids adsorption, blockage and damage, reduces cost. Easy Maintenance Strong Anti-Interference Capability Modular design, laser module field replaceable, easy maintenance Adopting wavelength-modulation-spectroscopy allows better signal/noise ration & anti-interference capability of dust and background gas.
