Calibration Services

OptoTest offers a variety of calibration services to meet customer demands for quality and efficiency.

Our in-house calibration department is capable of servicing the full range of OptoTest equipment and can provide a full spectrum of troubleshooting and repair services. In the on-site version, a member of the OptoTest team performs the calibrations at the customer site. In the remote version, we supervise and perform the calibration remotely with assistance from an operator on the customer side.

OptoTest and its certified calibration centers can verify unit adherence to stated specifications and perform calibrations to bring units back into specification should they fail. OptoTest can provide re-calibration service to our entire product line, including specialized equipment, custom products, and Return Loss modules. Certified calibration centers can perform re-calibration for most standard products. For more information contact OptoTest.
