With a licence to test: Specidur®-CO for AU test gases from Westfalen.
Do you calibrate devices for exhaust gas testing? Do you need test gases with a calibration certificate for this? Then Westfalen is the right partner for you! Our Specidur® CO for AU series meets the highest quality requirements and can be ordered quickly and easily via our online shop.
Clear rules apply to exhaust emission tests: Since 2019, exhaust gas measuring devices are required to be calibrated by an accredited provider in accordance with the standards. This requires test gases that are accredited in accordance with DIN ISO/EC 17025. Our Specidur® series meets these requirements and is supplied with a DAkkS calibration certificate. In addition, the German Accreditation Body (DAkkS) has accredited us as a manufacturer of certified reference materials in accordance with DIN EN ISO 17034. This means that our special gases centre has provided proof of competence at the highest national and international level.
The calibration certificate displays the test result of your gas. In addition to the measurement results and the measurement uncertainties, it also lists the calibration procedure, the measurement conditions and the reference standard. Furthermore, the calibration certificate documents the traceability to national standards.
Our 3-litre bottle for your test gases is lighter and more handy than the conventional 10-litre container, so it is ideal for mobile use when testing the AU testers. In addition to two or three gas cylinders, a pressure reducer and a hose for gas extraction fit into the transport case. The 3-litre bottle is UN-marked, so it can be transported by sea and air.
