Many people are unaware that taxpayer-funded State operated metrology laboratories (e.g., State Dept. of Agriculture) offer inexpensive calibration of weights (aka mass). | Having weights (mass) re-calibrated by a commercial metrology (calibration) laboratory is often cost prohibitive (i.e., it's cheaper to purchase new certified weights). However, many taxpayer-funded State operated metrology laboratories (e.g., State Dept. of Agriculture) offer inexpensive calibration of weights (aka mass). Check the fees from your State Metrology lab before purchasing new weights. |

Recommended calibration intervals for mass standards for Echelon III calibrations//" provides for good __initial__ calibration intervals. Where check weights (mass) are only used to calibrate (or verify) the accuracy of weighing scales 2 or 3 times a year, these are typically placed on an extended calibration interval due to their seldom use and minimal wear (provided that they're not mishandled or damaged). |
