CEMS
Turnkey continuous emissions monitoring designed, built, and integrated in-house — certified hardware, DAHS software, and regulatory support under one roof. From first design through years of service, one team owns it
Vertically integrated emissions compliance
CEMS & PEMS emissions monitoring One partner. Total ownership.
Air emissions monitoring, owned end to end — so staying compliant is one less thing you have to manage.
What we do
CEMS, PEMS, Trace DAS, and the services behind them
PS-16 specialists
PEMS
The PS-16 experts in predictive emissions monitoring — we built our system around EPA Performance Spec 16, the standard a PEMS has to certify to, and pioneered the first approved PEMS in double-digit U.S. states. A software-based alternative to CEMS that cuts hardware and maintenance costs, all on our Trace DAS platform
Trace DAS
Our data acquisition and handling platform — the software layer that turns raw analyzer signals into compliant records, fully configurable calculations, and EPA-ready reports. The same DAHS behind every Trace CEMS and PEMS, on a secure web architecture that scales from a single source to a fleet
How we work
One partner for the entire lifecycle
Trace is a vertically integrated leader in air emissions monitoring — we engineer, build, install, and service every CEMS and PEMS in-house. One accountable partner owns the outcome for the long term: the buck stops with us, with no change orders or finger-pointing.

We engineer, build, install, and certify it in-house — then keep it running with ongoing service, parts, and support.
