As the regulatory landscape for particulate emissions continues to evolve, ensuring traceability and confidence in measurement quality has generated significant interest among industry professionals. This requires regular maintenance and calibration of the reference equipment used to measure key parameters such as particle number concentration (PN), with increasing focus on uncertainty assessment.
Maintaining the accuracy and reliability of your Engine Exhaust Condensation Particle Counter (EECPC) is essential for meeting regulatory requirements and ensuring high-quality emissions measurements. TSI’s service offerings, which include cleaning, calibration, and repair, provides the preventive and corrective maintenance needed to keep your EECPCs in top working condition.
Value of Clean & Calibrate and Repair Services
TSI’s standard services, Repair, Clean & Calibrate, Clean & Calibrate, offer essential maintenance and calibration for models such as the 3790A and 3790A-10. These services ensure that your instrument remains compliant with regulations, including UNECE PMP (Particle Measurement Programme) as outlined in European Regulations UNECE No. 49 and No. 83. Additionally, these calibration services follow the guidelines of ISO 27891 for CPCs, which is critical for ensuring accurate aerosol particle number concentration measurements.
ISO 17025-Accredited Calibration
For those seeking the highest level of traceability, TSI also offers ISO 17025-accredited calibration services for EECPCs. This accreditation still ensures compliance with PMP and ISO 27891 while meeting the highest technical standards for traceability and uncertainty assessment. ISO 17025 accreditation includes a detailed analysis of measurement uncertainty, providing the highest confidence in instrument calibration possible. This service is especially valuable for regulatory organizations and laboratories that need to maintain a broader ISO 17025-compliant quality program.
PMP Compliance and Calibration for Reference Instruments
In addition to servicing EECPCs, TSI also offers PMP-compliant calibration for reference instruments like Models 3750, 3772, and 3068B. Properly calibrated reference instruments are critical for maintaining a PMP-compliant internal calibration bench, ensuring that particle number counting systems meet regulatory standards. These calibrations, although not ISO 17025 accredited, include additional procedures over the standard options, such as counting efficiency measurements and linearity checks for concentration accuracy.
By choosing TSI’s comprehensive calibration and maintenance services, you ensure that your EECPC and reference instruments continue to deliver precise and compliant emissions measurements year after year.
