Current air monitoring methods are expensive, provide limited data, and time-consuming, which can result in high levels of resampling. Companies often have to overspend on health and safety equipment, engineering controls, and workers compensation insurance. Furthermore, companies are at risk for fines from OSHA.

Technology Solutions

World’s smallest wearable exposure monitors to help protect workers from exposure to airborne pollutants such as respirable particulates during work activities. Platform for Environmental Health and Safety monitoring enabling remote monitoring, advanced sensing, proprietary data inversion algorithms, and analytics. Advanced air purification systems for use as engineering controls to maintain proper air quality.


Using APT’s exposure monitors, safety engineers can track exposure risks in real time allowing workers to take simple steps to remediate overexposure thus reducing the risk of OSHA violations, workers compensation liability, and overall resampling costs.
