Instrument Calibration &
State-of-the-Art Metrological Services
Our state-of-the-art metrological services and ISO 17025 accredited calibration laboratory are available to solve your measurement challenges. Whether you need instrument calibration services, temporary test instruments to conduct a performance test, wind tunnel testing, or expert metrology consultations, McHale’s Measurement Services can provide the solutions your project needs — with NIST traceable instrument calibration behind every result.
Why NIST Traceable Calibration Matters
Every instrument McHale calibrates or rents is backed by NIST traceable instrument calibration, meaning results can be traced through an unbroken chain of comparisons back to national measurement standards. For power plant performance testing, that traceability is what makes test results defensible and contractually acceptable to every party involved.
