The HPM Series particle sensor monitors HVAC units and consumer air technology for potentially harmful particulate contaminants caused by dust, soot, and smoke. Uses lasers to monitor for fine inhalable particles up to 2.5 micrometers in diameter, roughly one-thirtieth the width of a single human hair.
Feeds information to HVAC control systems or other monitoring devices to alert FMs, who can then activate air purification, bring in outdoor air, change a filter, or simply investigate further.
