    External calibration Balance

    Overview Products Knowledge Standards Terms
    The external calibration of balances is performed by metrological institutions using standard weights to verify weighing accuracy. This process is used for regular verification of instrument performance in laboratories to ensure the reliability of test data. In industries such as coatings and inks, it is essential to maintain metrological traceability during the weighing of raw materials.
    Selection
    When selecting an external calibration balance, it is necessary to confirm the qualifications of the calibration institution and ensure that the calibration range covers the commonly used weighing intervals. Verify the balance's repeatability and eccentricity error data, and ensure its environmental adaptability meets the laboratory's temperature and humidity conditions. The calibration cycle should be determined based on the frequency of use.

    This article introduces the key points for selecting an electronic balance. It provides a detailed list of core parameters such as accuracy class, repeatability, and linearity error, and explains their impact.
    Summary of Balance Selection for Different Application Scenarios
    This article discusses how to choose a balance based on usage needs. First, you need to understand the basic parameters of a balance, such as its maximum capacity and precision.
    Grade classification of balances based on different repeatability indicators
    The repeatability of a balance refers to the consistency of multiple weighing results for the same load under identical conditions, which is a key indicator for evaluating the performance of a balance. It is typically expressed as the standard deviation or range, with smaller values indicating greater stability and reliability of the balance.
    Selection criteria for linearity error of semi-micro balances
    The linearity error of a semi-micro balance refers to the deviation between the actual displayed value and the theoretical value within its weighing range. This indicator directly affects the accuracy of weighing, which is particularly important in scenarios requiring high-precision measurements, such as material analysis or environmental monitoring.
