ISO 17025 Calibration Lab

TESCO’s ISO 17025 Calibration Lab is a metrology laboratory accredited to ISO/IEC 17025:2017 Electrical DC & Low-Frequency calibrations and testing as well as NIST and other SI traceable calibrations. The accredited scope applies to the general competency for conducting energy measurements as well as precision high current and high voltage transformers. We are one of the first in our industry to have an ISO/IEU 17025:2017 scope to calibrate and test laboratory reference transformer standards.

We can calibrate and repair any equipment of any vintage from any manufacturer including:

  • Hand Held Multimeters and Field Test Equipment
  • Field Meter Test Equipment
  • Field and Transfer Standards
  • Electric Meters
  • Instrument Transformers
  • TESCO now offers an ANSI/NCSL Z540.3:2016 standard calibration or an ISO 17025:2017 calibration. We can test individual items or prepare a blanket program to calibrate all or your equipment.
