Accredited Calibration Services in the US

Lab & field accredited calibration for flowmeters, pressure sensors and temperature devices

Calibration ensures that instrument measurement is accurate and within the limits required to produce a quality product. This helps reduce overall business costs by minimizing quality fluctuations and associated costs. For some processes, periodic calibration to NIST standards is a requirement to comply with both quality and safety standards. We can help you stay in compliance while reducing your costs and increasing process up-time. Learn more by watching the video at the bottom of the page!


  • Calibration for flow, temperature and pressure - on all manufacturers' instruments

  • A2LA accredited field and laboratory calibration services available in accordance with ISO 17025

  • Flowmeters will include line sizes up to 2” (rig) and 3” (in-line) with the following uncertainties: Mass (e.g. Coriolis ± 0.12%), volumetric (e.g. Magmeters and Vortex ± 0.17%)

  • NIST traceable master flowmeter

Endress+Hauser earns ISO 17025 certification

A2LA accredited calibration facilities are located in Greenwood, IN and Pearland, TX. Accreditation covers both laboratory calibrations in Greenwood and LaPorte as well as field calibrations at a customer’s location.

Scope of accreditation

The scope of accreditation includes the principles of flow, pressure and temperature for both laboratory and on-site calibration. Also included within the scope are electrical parameters associated with current, voltage, resistance and frequency pertaining to internal laboratory calibration. Please refer to the Scope of Accreditation for specific measuring capabilities by visiting www.a2la.org (search “accredited organizations” for Endress+Hauser).
