We understand the nature of Metrology is specialized, which demands competence that spans thousands of different measurement instrumentation across many different processes and industries. That is why we work closely with you to satisfy your unique requirements. Northwest Metrology offers:

  • ISO/IEC 17025 accredited laboratory.
  • OEM quality calibrations.
  • Walk-in drop off & pick up at our Laboratory in Bakersfield.
  • Consultation with expert Metrologists with over three decades of experience.
  • All calibration levels available: ISO/IEC/ANSI/NCLS with or without data and with or without accreditation. 
  •  Repairs of various instrumentation & equipment.
  • 38’ mobile laboratory with RFI/EMI shielding & rigid environmental controls.
  • Mobile Van for versatile on-site service and accessibility.
  • Mobile pickup and delivery (where available).
  • Dependable turnaround times (expedite service available on request).
