Optimal Air Testing offers a full range of air emissions testing services to a variety of industries, such as:

  • Power (public) Utilities
  • Industrial & Hazardous Waste Incinerators
  • Metallic Mineral Smelters
    & Processing Facilities
  • Acid & Fertilizer Plants
  • Semi-conductor Facilities
  • Industrial Manufacturing Plants
  • Portland Cement Plants
  • Petrochemical & Ethanol Refineries
  • Glass & Mineral Wool Facilities

Sampling procedures performed on a regular basis include methods listed 40 CFR Parts 51, 60 and 63
for measurement of criteria pollutants, acid gases, and hazardous air pollutants.


Individually and as a group, the staff has an industry wide reputation for providing the full spectrum of services and data of the highest quality with an emphasis on safety. Optimal offers a thorough knowledge of EPA test procedures and regulatory requirements. This experience is helpful when innovative modifications are needed measuring non-standard compounds, processes and/or facilities, and it is invaluable on-site if decisions must be made without regulatory pre-approval.

Our team of professionals is the strength of Optimal Air Testing. The company is lead by Dan Klassen and Jeff Pye. Combined they have over 30 years experience measuring emissions from stationary sources.


Optimal Air Testing is committed to providing well-maintained equipment with state-of-the-art technology. All equipment has been in service less than two years, and was chosen for accuracy as well as reliability and efficiency. Wet chemistry/isokinetic equipment is mobilized in vehicles customized to improve organization and efficiency when arriving on-site. Our mobile labs are equipped with extractive O2, CO2, NOx, CO, SO2, and VOC (total hydrocarbon) continuous emission monitors.

Optimal can provide fully automated continuous emission monitoring systems (CEMs) to collect velocity, temperature, O2, CO2, SO2, NOx, CO and VOC's data. Our mobile temporary CEMs laboratory was designed to collect data for periods longer than 7 days. The system will perform automated daily calibrations and, with remote monitoring, eliminates the need for an on-site technician.
