The instrument is low in production cost and measures micro-density air pollutants accurately.

In this regard, Jong Sang Hyon, director of the Institute of Medical Science, told KCNA:

Researchers of the institute fully solved technical problems arising in manufacturing the measuring instrument.

They newly designed a real-time air pollution monitoring system, which can measure pollutants in the air and atmospheric temperature and humidity in a comprehensive way.

They also developed a classifier to measure the density of materials harmful to human body in air dust.

And the research group of Kim Chaek University of Technology made a drive circuit of gas sensor for the environmental measuring instrument.

Its application proved that all measurements reached the world level in accuracy.
