Mass Calibration Services in Los Angeles

Fulfilling Customers’ Calibration Needs Since 1978

Micro Quality Calibration’s (MQC) mass standards calibration laboratory was constructed and designed to meet the recommended procedural and environmental practices as detailed in International Organization of Legal Metrology (OIML) and National Institute of Technology (NIST) standards for the calibration of mass.

Our weight sets and individual weights calibration capabilities range from 1 mg to 40 kg (Echelon 2) with accuracies from ASTM Class 0 to 7, OIML E-1 through M-3, which help guarantee that MQC can service a vast range of customers. The American Association for Laboratory Accreditation (A2LA) accredited our labs to ISO/IEC 17025 for mass calibrations. Feel free to browse our accreditations in order to better understand our uncertainties and ranges.

Our Weight Calibration Service Capabilities

MQC’s mass standard calibration laboratory is climate controlled, with the humidity maintained at approximately 40% and the temperature kept at 68° F. A dedicated, circulatory HVAC system supplies internal air to the laboratory, which is fully enclosed. This helps maintain the lab’s stringent environmental controls and reduce any airborne materials.

We make sure all weights are given an adequate period of temperature stabilization so that they can properly acclimate to the laboratory. To help reduce vibrations to nonexistent levels, our mass calibration laboratory is stocked with state-of-the-art equipment, such as our granite weigh tables designed for the Sartorius mass comparators.

MQC calibrates mass precision calibration weights to all ASTM and OIML specifications / requirements / recommendations. The value of a general purpose weight gradually decreases as the body and paint deteriorate and the adjusting material oxidizes. When the difference from the nominal specified value approaches the maintenance limit, adjustment will be required. Let MQC calibrate, repair, and certify your weights.
