We perform traceable calibration of instruments
Monitoring is one thing, monitoring correctly is another. To ensure that instruments monitor correctly within given tolerances, they must be calibrated regularly. OPSIS provides calibration services that can be performed both in our certified laboratory and at our customers' premises.
CALIBRATION FUNDAMENTALS
'Calibrating a gas' means comparing a known gas concentration with what an instrument reads when exposed to that gas. The instrument's zero level and amplification factor can then be adjusted to match the known gas concentration. Strictly speaking, the calibration is just a comparison. The adjustment follows the calibration.
For monitoring purposes, there are often regulatory requirements on when and how calibrations should be performed, and if and how the instrument should be adjusted. In many cases, it is also important that the instrument measures correctly in process control applications.
CALIBRATION AT THE LAB AND ON THE ROAD
OPSIS has a large and well-equipped laboratory to perform instrument calibrations of all the gaseous compounds that OPSIS instruments can monitor. Gases and other reference materials used in the calibrations are always traceable to national and international standards.
OPSIS also has vehicles fully equipped with everything needed to perform the most common types of calibrations in the field. In practice, it means calibration of our customers' monitoring systems at the monitoring site.
The instruments do then not need to be sent to OPSIS for calibration, which saves time and eliminates risks of transport damages. Our customers do not need to own or handle calibration gases themselves, nor do they need to allocate their own resources to perform the calibrations.
We issue the calibration certificates needed for reporting to regulatory authorities and other stakeholders.
ACCREDITED CALIBRATIONS
Both the OPSIS calibration laboratory and the calibration activities in the field are accredited for calibration of a wide range of gases as well as particulates, compliant with the competence requirements set in the ISO/IEC 17025 standard.
For additional quality assurance, most of our calibrations can therefore be carried out under accreditation, both when performed at our laboratory and at our customers' sites.

OPSIS systems for continuous emissions monitoring have been successfully evaluated by the German test institute TÜV for calibration as rarely as once a year.
