    MicroBalance

    Overview Knowledge Standards Terms
    Microbalances operate on the principle of electromagnetic force balance, precisely measuring minute mass changes through variations in electrical current. They are used in laboratories for weighing milligram-level samples, detecting pigment addition amounts in the coatings industry, and measuring solvent evaporation residues in the ink industry.
    Selection
    When selecting, focus on models with a weighing range that covers the sample weight, reading accuracy that meets testing requirements, minimal impact from environmental temperature fluctuations, matched calibration weights, a draft shield structure to reduce airflow interference, and a short stabilization time for better suitability.

    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.
    Weighing lower limit of microbalances and selection basis
    The lower weighing limit of a microbalance refers to the minimum mass that can be measured while ensuring accuracy, which is crucial for the reliability of experimental data. It is influenced by factors such as sensor sensitivity, structural resistance to interference, and environmental stability.
    Repetibility Test Method and Weights for Semi-micro Balances
    This article discusses the method for repeatability testing of semi-micro balances and the use of weights. Repeatability refers to the consistency of the balance's results when weighing the same object multiple times under the same conditions, which is crucial for the reliability of experimental data.
    Analysis of Causes for Excessive Repetition Error in Microbalances
    Microbalance repeatability out-of-tolerance refers to the situation where the results of multiple weighings of the same object exceed the allowable range of variation.
