PEMS & In-use Testing Research


CE-CERT has considerable experience with successfully completing complex projects that involve elements of laboratory testing, field work, activity measurements, and PEMS evaluations and implementations. CE-CERT was the primary contractor for the in-use validation of all PEMS evaluated in the Measurement Allowance (MA) program for both gaseous and PM PEMS. As part of this program, CE-CERT played a significant role in identifying the inadequacies of PEMS during in-use testing, and worked with PEMS manufacturers over several generations of the technology to resolve these issues. Over the course of this program, CE-CERT gained a reputation as being one of the leading institutions in the operation and evaluation of PEMS.
