The Weights and Measures program operates a Metrology Laboratory located in Giddings.  All weights and measures calibrations are documented and traceable to International System of Units (SI) through the National Institute of Standards and Technology (N.I.S.T.). The Giddings Metrology Laboratory is recognized by NIST in Mass Echelon III and Volume Echelon Transfer II.

LAB OPERATIONS OVERVIEW
The State Metrology Lab (Giddings Metrology Lab) conducts mass and volumetric calibrations on field test standards used by Licensed Service Companies and Texas Department of Agriculture (TDA) Inspectors and other customers that utilize commercial weighing or measuring devices as described in Agriculture Code §13.113.  Due to the high demand for field standard calibrations, appointments for calibration must be done several weeks in advance, through submission of TDA form RMT-001 and the required accompanying documentation.
