We conduct emission measurements for a wide range of parameters including NOx, CO, CO₂, SO₂, formaldehyde (HCOH), NMNEHC, THC across natural gas-fired engines, turbines, heaters, emission control devices (ECDs), and thermal oxidizers.

In addition to testing, Oasis supports clients in meeting EPA CEDRI submission requirements. Utilizing our proprietary WinStack system, we can often complete the testing and deliver a summary report on the same day—providing immediate assurance that the source meets applicable EPA standards.
