Environmental Chamber Qualification

Complete Qualification services are generally a three-part process.

Part One: The Installation Qualification (IQ) provides documentation stating that the fundamental aspects of the chamber meet or exceed the design, procurement, and installation needs.

Part Two: The Operational Qualification (OQ) is utilized for providing documented verification that the systems and subsystems perform as intended at all anticipated operating ranges (normally performed with an unloaded chamber).

Part Three: The Performance Qualification (PQ) provides documentation verifying that the environmental chamber works as it’s intended to, and that it works in the correct manner. This is typically verified either with a simulation or when the chamber is actually in use.

Environmental Chamber Testing – Environmental Chamber Calibration

Environmental Chambers often need more than just service and repair, we also provide environmental chamber testing and calibration. Environmental Chambers need to meet and adhere to certain specifications to protect the quality of specimen and products and to ensure that processes are accurate.

We understand the critical role that calibrations have in your regulated industry, which is why we use extremely precise calibration standards. The application of these standards will ensure that your system is highly calibrated (NIST National Institute of Standards and Technology), in order to meet or exceed manufacturer’s specifications.

We also offer tailored services such as loop calibrations or single point calibrations and verifications. Our procedure provides a 3-point “as-found” calibration verification. The “as-found” readings are documented and verified to be within the manufacturer’s tolerance, if found within the tolerances the device is then returned to service. If any instrument exceeds the tolerance, we will promptly notify you, so that you may take the necessary steps to document the event.

Additionally, if the “as-found” readings are not within the manufacturer’s tolerance, the instrument is then calibrated using the manufacturer’s calibration procedure. After completing the calibration, the instrument’s “as-left” readings are documented using the same three points from the calibration verification to ensure the instrument is reading within the manufacturer’s tolerance.
