Product Overview
Adopting TDLAS (Tunable Diode Laser Absorption Spectroscopy) technology, the LT-9000 in-situ direct-insertion laser oxygen analyzer can be directly installed on pipelines, reactors and other process equipment. Complicated sampling and pre-treatment are not required, enabling real-time online measurement of oxygen concentration. Featuring fast response and strong anti-interference capability, the instrument performs stably and reliably under harsh working conditions such as high temperature and heavy dust. It supports communication with DCS systems to realize data uploading, over-limit alarm and interlock function. It provides accurate and reliable measurement data for safety production, process optimization and explosion-proof monitoring in chemical, petrochemical, pharmaceutical and other industries.
