Calibration Information

AlphaLab Inc. meters are shipped calibrated to their specifications. Certain meters include a calibration certificate. For most meters a calibration certificate is an option (fee applies). Recalibration for most types of meters is not required within 10 years. Accuracy of the meters is guaranteed to within the specifications whether or not a certificate is issued.

For meters that come standard with a  calibration certificate, the calibration (and any recalibration) is done according to ISO/IEC 17025:2005 using standards within dated calibration intervals. The uncertainty (inaccuracy) of the standards is equal to or less than ¼ of the inaccuracy published for each type of meter. For example, a meter with accuracy (inaccuracy) of +/- 2% is calibrated with a standard with in accuracy of +/- 0.5% or less. Standards are traceable to NIST and/or fundamental physical quantities.

We can perform calibrations at any time; each calibration includes a NIST-traceable certificate if applicable. The calibration fees vary between meters. Most calibration services can be performed within one week of receiving the meter. Calibration services can only be performed for meters manufactured by AlphaLab Inc.
