Langsi Sensing Technology (Shenzhen) Co., Ltd. is a national high-tech company specializing in laser spectroscopy technology. The company was established in 2020, based on the innovative technology accumulation of the Chinese University of Hong Kong in the field of laser spectroscopy. It independently develops and produces high-precision laser gas analyzers, gas sensors, industrial data cloud IoT, and professional laser module products in Qianhai, Shenzhen and Hong Kong, China. Its application areas cover industries with gas quantitative analysis needs such as ICOS hydrogen concentration monitoring, energy digitization, scientific experiments, low altitude economy, urban security, smart agriculture, and atmospheric environmental protection.

Langsi Technology has independently mastered a complete set of spectral technology routes from mid infrared laser spectroscopy (CRDS, CEAS) to near-infrared laser absorption spectroscopy (TDLAS), photoacoustic spectroscopy (PAS) to LED optical sensors. Currently, it is mainly used in the field of gas concentration quantification analysis.

Under the national strategic demand of "peak carbon emissions and carbon neutrality", Langsi Technology has independently developed the domestically produced high-precision greenhouse gas laser analyzer MT-01. Based on the self-developed cavity enhanced CEAS technology, it meets the WMO international standards and achieves real-time and accurate measurement of carbon data (CO2, CH4, N2O) at ppb level in atmospheric environment and industrial scenarios. It has passed the Shanghai group standard comparison test and promoted the establishment of China's carbon monitoring technology standards.

The Longfor WES series sensors, with their advantages of low power consumption, small size, and long standby time, can be mounted on drones and mobile vehicles for mobile environmental and meteorological monitoring, capturing concentration distribution maps of various gases (CO2, CH4, CO, SF6, NOx, H2S), and connecting to the cloud in real-time through 5G/NB IoT to display multi-dimensional gas measurement information. At present, the joint monitoring pilot of Langsi Technology's instrument sensors has covered government regulatory units such as Shanghai Environmental Monitoring Center, a large-scale chemical park's "carbon pollution co measurement" project, and meteorological research needs such as Fudan University and Hong Kong Polytechnic University.

Langsi Technology continues to tap into the enormous value of laser spectroscopy in real-time, precision, and non invasiveness, creating domestically produced analytical instruments and sensors to provide new quality productivity for gas quantification analysis needs in fields such as environmental and industrial emission monitoring, clinical breath analysis of lung diseases, marine and space exploration, and scientific experiments.
