nCLD 66 used for on-road Portable Emissions Monitoring Systems (PEMS)
Ahmad Nabiyar • June 17, 2020
ECO PHYSICS nCLD 66 NOx analyzer was used to conduct on road NOx emissions measurement from heavy duty diesel trucks.
Portable Emissions Monitoring Systems (PEMS)-chasing experiments were conducted in China for twelve heavy-duty diesel vehicles (HDDTs) to evaluate the accuracy of mobile measurement results. Two data processing approaches were integrated to automate the calculations of fuel consumption-based emission factors of nitrogen oxides (NOX).

ECO PHYSICS recently visited the NASA Glenn Research Center in Cleveland, Ohio. Glenn is NASA’s only research center in the Midwest, officially named after John Glenn in March 1999. This site was established in 1941 and was incorporated into NASA in 1958. It is NASA’s third oldest research center. The purpose of the facility has evolved over the years, it was originally for aircraft propulsion studies and now it creates advanced technology for aviation and space exploration. Their facilities currently include wind tunnels, drop towers, vacuum chambers, and a research aircraft hangar. We were fortunate enough to see some of these and take some photos during our installation and training visit. Glenn is involved with many important projects, such as the International Space Station and the Artemis Program, which is NASA’s latest plan to return to the Moon. We hope to be involved in more of the great work and research that NASA Glenn will do in the future. Thank you to Krystal and Dawn for their time.
Fall seemed to turn to winter quickly for us this year!
We hope you have had a good summer and are ready to get back to the business of measuring NOx!
As summer begins it's last month, take some time to relax and rejuvenate.
We commemorate the 159 years since freedom finally reached enslaved Black Americans in Galveston, Texas. Let's continue the work to make sure that freedom is truly there for all Americans.
Meet us in Scottsdale, AZ May 21-23 for the Continuous Emissions Monitoring User Group (CEMUG) Meeting!
