Instrument Calibration

Accredited or Standard Calibration?

Quest Technologies calibration and service laboratory is the only factory authorized service center for Quest brand instruments in the United States.  Many of our products are used in potentially explosive atmospheres and require strict adherence to our original proprietary design specifications for service and repairs.  Many things can void intrinsic safety such as installing the wrong battery or unauthorized repair.

In order to ensure best instrument performance over time and in the event of inspection, audit, or litigation, we recommend the instrument be recalibrated annually.  Any number of factors may cause the calibration item to drift out of calibration before the recommended interval has expired.

Accredited Calibrations
Why are Accredited Calibrations important?
  • Provides validation of data if challenged during litigation
  • Ensures that intrinsic safety has not been compromised
  • Provides confidence in the technical competency of the lab calibration

Working directly with our Calibration and Service Laboratory; accredited by A2LA to ISO/IEC 17025, you are guaranteed to receive the following as part of an accredited calibration:
  • Record of incoming “As Received” data & “Final Condition” data
  • One-year warranty extension on currently manufactured products
  • Factory Hardware and Firmware updates automatically installed
  • Fully trained technicians competent to service and calibrate every piece of equipment
  • NIST traceable calibration certificate
  • Compliance with ISO 17025 and ANSI Z540
  • Quick turn-around with rush service available
  • Peace of mind that your service has been performed properly
Standard Calibrations

If your needs don’t warrant or require an Accredited Calibration, Quest Technologies also offers a standard calibration.  A standard calibration includes the following:

  • Factory Hardware and Firmware updates automatically installed
  • Acoustic, Sensor & Electronic calibrations
  • NIST traceable calibration certificate
  • One year warranty extension on currently manufactured products
  • Peace of mind that your service has been performed properly.
