On September 25, the three-day China (Shanghai) International Sensor Technology and Applications Exhibition was concluded.

SIGAS with the latest research and development results "ultraviolet spectral trace detection technology" re-appeared in SENSOR CHINA, while bringing sensor products, a variety of industrial-grade infrared UV gas analysis sensors.

Mr. Andreas Hester, Research and Development Director, SIGAS

"Ultraviolet photoacoustic spectroscopic trace detection technology."

(Based on the infrared photoacoustic spectral structure)

Photoacoustic spectroscopy is a new spectroscopic technology based on the photoacoustic effect, which is different from traditional infrared spectroscopy technology. It effectively converts optical signals into acoustic signals and calculates the final gas concentration by detecting sound signals by precision microphones. This method can efficiently collect weak photoacoustic signals and virtually eliminate background signals' interference due to the unique optical structure of photoacoustic spectroscopy technology and the special calculation process in the signal acquisition and signal processing process. It is very suitable for trace gas concentration detection field and non-interference detection in a complex environment.

SIGAS received the Sensor China Outstanding Partner Award.
