The Airtec monitor is an elemental carbon monitor designed to determine exposure of workers in underground mines to diesel particulate material (DPM). Airtec uses a real-time particle capture and light-transmission method to yield elemental carbon values which closely correlate with NIOSH 5040 test results. The Airtec monitor provides results that are time-and-space-resolved, allowing the operator to track DPM levels over time to help eliminate the risks associated with over exposure.


Wearable, Real-Time DPM / EC Monitor Replicates NIOSH 5040


  • Instant Results

    Get real-time results that you can store for later analysis. No need for filters to send to an outside lab

  • Increased Safety For Workers

    Airtec has high sensitivity to DPM and can track levels over time to determine the possibility of long-term health hazards.
