BLATN BR-HOL  Professional Handheld Air Detector


BLATN BR-HOL series handheld air detector is a high-precision air quality testing instrument which jointly developed by BLATN and Meteorological Monitoring Center of China Meteorological Administration.

Its predecessor is dust-free testing equipment in operating room of field hospital. To accurately detect PM1.0, PM2.5, PM10, formaldehyde, ozone, negative ions, ionizing radiation, carbon dioxide, temperature and humidity data.

Combined the Fourier Exchange, Particle Swarm Optimization Algorithm and empirical data, to bring out an exclusive patented POS-VTM algorithm, and acquired the authorized comparison report from Institute of atmospheric composition. The core technology of BR-Hol series air detector, has won a number of science and technology awards.
