Understanding Calibration Certificates

A calibration certificate is a formal document issued by a qualified laboratory, verifying that a measuring instrument meets specified accuracy standards by comparing it to a known, traceable standard. This certificate provides crucial information, including the measurement results, the uncertainty of those measurements, and details about the reference standards used during the calibration process. Its primary purpose is to ensure the reliability and accuracy of instruments, offering documented proof of their performance and traceability to national or international standards. For professionals in industries reliant on precise measurements, a valid calibration certificate is indispensable for maintaining quality control, complying with regulations, and ensuring confidence in their data.

NIST Traceability for Your PressureWorx Products

For products available through PressureWorx, NIST (National Institute of Standards and Technology) traceability means that the calibration of your instrument can be directly linked back to measurement standards maintained by NIST. This traceability is critical for industries where measurement accuracy has significant implications for safety, quality, or regulatory compliance. When you receive a NIST-traceable calibration certificate with your PressureWorx product, it assures you that the instrument's readings are consistent with national measurement standards, providing an unbroken chain of comparisons. For example, a Wika pressure transducer purchased with a NIST certificate guarantees that its pressure readings conform to established benchmarks. Similarly, a Bellofram precision air regulator with NIST certification ensures its output pressure is verified against a national standard, vital for critical control applications.
