Ozone Chamber and Ozone Monitor Calibration

Ozone Chambers and Monitors: Calibration & Service

Ozone Research Equipment Company (OREC™), now located in Akron, Ohio, are the manufacturers of OREC™ Ozone Test Chambers, OREC™ Ozone Test Chamber Accessories and OREC™ Ozone Monitors.

The instruments, manufactured by CCSi, continue to bear the OREC™ name and be constructed with the same components, processes and attention to quality for which OREC™ has become renowned.

OREC™ now also features a full service ISO Certified Calibration Laboratory to accommodate OREC™ Ozone Monitors and Chambers, as well as those of other manufacturers.

Additionally, OREC™ has recently achieved NIST direct traceability for the measurement of ozone concentrations. On a global scale, OREC™ is one of a very few manufacturers of ozone instruments to have direct NIST traceability.

OREC™ Ozone Monitors, Model DM100, Serial Numbers 318 and 748 were certified as a first level calibration source with primary traceability to NIST. Through the NIST Calibration Program, the testing was performed, and the reports prepared, by NIST at their laboratory in Gaithersburg, Maryland on July 7, 2003. OREC™ Ozone Monitor, Serial Number 748, was calibrated again on September 7, 2005.
