Particle Sensor Exploits Laser Tech

Based on laser technology, the HPM series particle sensor monitors air for potentially harmful particulate contaminants caused by dust, soot, and smoke. It uses a light-scattering method to accurately detect and count particles in the concentration range of 0 micrograms-per-cubic-meter-of-air (µg/m3) to 1,000 µg/m3 in a given environment. The sensor then analyzes the particulate size and concentration in real time to enable systems to provide alerts and allow operators to take remediation actions. The sensor is also incorporated in the company’s PM2.5 Indoor Air Quality Detector, a portable air monitor for consumers in China. It can detect contaminants smaller than 2.5 µm in diameter, or one-thirtieth the diameter of a human hair.
