Sharp、Accuracy、reliability

Accidents remind us that the intelligent control of gas leakage detection is so important.

The application products of Hanhai photoelectric's laser spectral absorption technology can actively monitor the risk nodes of gas leakage without waiting for the gas to diffuse to the equipment and change from passive to active.

01 high sensitivity

Trace gas leakage can be accurately detected and the reaction speed can be less than 0.1 second. It can prompt at the early stage of hidden danger and change the alarm into early warning

02 high monitoring accuracy

It can achieve "fingerprint" detection, provide reliable and accurate monitoring data, 0 false positives and completely eliminate false positives

03 strong anti-interference ability

It will not be disturbed by humidity, dust, temperature and other gases, and can work in high humidity environment for a long time

04 stable

Long term stable operation, safer and more reliable.

Hanhai photoelectric laser absorption spectrum gas monitoring products truly achieve the sensitivity, accuracy and reliability of gas detection! Escort the safety of people's lives.

Hanhai photoelectric laser absorption spectrum gas monitoring products

It will appear in the exhibition of China combustion Association

Hanhai optoelectronics will participate in the 2021 (24th) China International Gas and heating technology and equipment exhibition from October 27 to 29, and will display the latest laser absorption spectrum gas monitoring products.

Hanhai optoelectronics is an industrial company brand of laser absorption spectrum gas detection technology of Chinese Academy of Sciences, which represents the technical height of China in this field. Its enterprise expert team includes academician of Chinese Academy of engineering, President of Hefei academy of material sciences, vice president of Institute of Optoelectronics of Chinese Academy of Sciences, etc. The series of products have been identified as "domestic leading and international advanced" by the State Administration of work safety (now the emergency management department). It is the only laser gas monitoring product that has passed the fire protection certification of the Ministry of public security, and has been jointly promoted by the Ministry of science and technology, the Ministry of industry and information technology, the Ministry of emergency and other ministries. It has won the second prize of national work safety science and technology, and has been included in the national "four one batch" project of safety science and technology, the directory of guidance on advanced applicable technology and products of work safety, the directory of promoting advanced and eliminating backward safety technology and equipment, and the directory of promoting advanced technology and equipment of work safety. The first national leading unit of laser gas detection product standard. It is the editor in chief of five group standards: portable telemetry laser methane detector, vehicle mounted laser inspection system, fixed reflection laser gas telemeter, fixed scanning laser gas telemeter and passive optical fiber laser leakage monitoring system. The series of products have been applied in large domestic energy enterprises and national key projects such as PetroChina, CNOOC, Sinopec, national pipe network, Beijing Gas Group, Ganghua gas group and China Resources Gas Group, and the world's largest laser gas leakage monitoring network has been built in Beijing.

Hanhai optoelectronics sincerely invites you to come to the site and let us provide you with more accurate gas monitoring solutions.
