Fend off unjustified community air quality complaints

Collect defensible data about your impact on surrounding communities' air quality.

How APT helps with community complaints

Set up real-time dust sensors along your fence line

Our wireless MAXIMA sensors measure dust concentrations on your site up to four times per minute.

Visualize how dust has moved outside your site 24/7/365

Get verifiable data on how your operation has or hasn't affected surrounding areas.

Generate reports to show that you're not impacting surrounding communities

Summarize your data into a professional report for community and air district leaders.

Know sooner whenever dust does cross your fence line

Instead of reacting when dust has already crossed your fence line, you can watch trends and take action before it's too late.


Powered by real-time dust sensors

Monitor your workforce with personal monitors, or entire areas with stationary monitors. We developed our monitors in-house to integrate seamlessly with our software.

Data quality

Independently tested and validated air quality data

We’ve partnered with AQ-SPEC and the EPA to guarantee reliable air quality data.

My goal is to have a defense.

I want to have all the [air quality] information over all four seasons. If we do get any complaints from our neighbors, I can say 'We've measured, and we're nowhere near the federal guidelines of the national ambient data quality'.
