Dr. Liu Ziyang from Anhui Lijian Defense gives a keynote technical report

Wang Mao, General Manager of Anhui Lijian Defense Technology Co., Ltd., Xue Lixin, Marketing Director, and Dr. Liu Ziyang participated in this conference with our company's independently developed QHZ4000 Fourier transform infrared spectroscopy gas telemetry imaging alarm system. Dr. Liu Ziyang gave a keynote technical report at the conference, introducing our company's hazardous gas telemetry series products and their application and solutions in the petrochemical industry.

Dr. Liu Ziyang from Anhui Lijian Defense introduced the QHZ4000 Fourier transform infrared spectroscopy gas telemetry imaging alarm system to the attendees

The QHZ4000 Fourier transform infrared spectroscopy gas remote sensing imaging alarm system is a high-tech intelligent optoelectronic gas detection equipment independently developed by our company. It adopts internationally advanced Fourier transform infrared spectroscopy remote sensing technology and can automatically detect and identify various chemical toxins (CWA), industrial toxic gases (TIC), volatile organic compounds (VOCs) and other toxic and harmful gases, flammable and explosive gases, and pollutant gases in real time and on a non-contact and large-scale basis. It provides 24-hour automatic video/spectral imaging monitoring, real-time warning, data+image+video comprehensive and intuitive display of gas dynamic distribution and diffusion trends, and fast traceability and positioning.
