Our team attended the National Association of Oil & Energy Service Professionals (OESP) Convention and Trade Show in Hershey, PA from May 19-23. The trade show drew a large crowd and we were delighted to interact with HVAC professionals and student technicians. We showcased our new flue gas analyzer. The Wohler A 400L Combustion Analyzer is reliable, affordable, and efficient. Show attendees loved its one-hand operation and vibrant display.
