Calibration Services

Miller-Weber has focused on accreditation and conforming to relevant industry standards to ensure that customers have a high level of confidence in all calibrations performed. The ISO/IEC 17025 Calibration Laboratory is housed in the Houston manufacturing facility and offers calibration services for thermometers, hydrometers and centrifuge tubes.

Why Use The Miller-Weber Calibration Laboratory?

  • Established traceability of measurement standards and measuring instruments to the International System of Units (SI) by means of an unbroken chain of calibrations linking them to relevant primary standards of the SI units of measurement.
  • Application of procedures to estimate uncertainty of measurement for all calibrations performed and the assurance that calibration uncertainties are sufficiently small so that adequacy of measurement is not affected.
  • We participate in annual assessment and proficiency testing activities.
