(A2LA Cert. No. 7067.01) 09/08/2025 Page 3 of 3 3 Field calibration service is available for this calibration. Please note the actual measurement uncertainties achievable on a customer's site can normally be expected to be larger than the CMC found on the A2LA Scope. Allowance must be made for aspects su ch as the environment at the place of calibration and for other possible adverse effects such as those caused by transportation of the calibration equipment. The usual allowance for the actual uncertainty introduced by the item being calibrated, (e.g., resolution) must also be considered and this, on its own, could result in the actual measurement uncertainty achievable on a customer’s site being larger than the CMC. 4 This scope meets A2LA’s P112 Flexible Scope Policy.

For the calibrations to which this accreditation applies, please refer to the laboratory’s Calibration Scope of Accreditation. Accredited Laboratory A2LA has accredited INTERNATIONAL SUPER SENSORS CORP Pomona, CA for technical competence in the field of Calibration This laboratory is accredited in accordance with the recognized International Standard ISO/IEC 17025:2017 General requirements for the competence of testing and calibration laboratories. This laboratory also meets the requirements of any additional program requirements in the calibration field. This accreditation demonstrates technical competence for a defined scope and the operation of a laboratory quality management system (refer to joint ISO-ILAC-IAF Communiqué dated April 2017). Presented this 8th day of September 2025. _______________________ Mr. Trace McInturff, Vice President, Accreditation Services For the Accreditation Council Certificate Number 7067.01 Valid to September 30, 2027
