Shanghai Xinzhuang Instrument Co., Ltd. is dedicated to developing the LNB brand, which is known for its energy-efficient and environmentally friendly features, as well as its leading position in the domestic market. As a professional manufacturer, the company ensures high-quality and cost-effective electronic balances that meet strict performance standards. When it comes to electronic balances used in gas fields or other critical environments, stability, sensitivity, accuracy, and repeatability are the four key performance indicators that users prioritize.
Stability refers to the consistency of the balance's measurement accuracy over time. A stable balance ensures reliable readings even after repeated use. Sensitivity, on the other hand, measures how quickly the balance reacts to small changes in mass. Compared to mechanical balances, electronic balances typically offer higher sensitivity, making them more suitable for precise measurements.
Accuracy is another essential factor, indicating how close the measured value is to the true value. Invariance, or the ability of the balance to maintain consistent readings under the same conditions, is also crucial. The smaller the fluctuation in readings, the better the invariance of the balance.
First, the invariance of an electronic balance’s indication refers to how consistent the results are when measuring the same object multiple times under identical conditions. This includes factors like repeatability, reproducibility, zero-point stability, and zero return error. Electronic balances also need to be checked for drift over time, especially when unloaded or loaded.
Second, correctness relates to how accurate the balance's readings are. It reflects the degree to which the displayed value aligns with the actual value, and it is closely tied to systematic errors in the measurement process.
Third, sensitivity determines how well the balance can detect small changes in mass. It can be expressed in terms of angular, linear, indexing, or digital sensitivity. For electronic balances, indexing or digital sensitivity is most commonly used. The lower the mass change the balance can detect, the more sensitive it is.
Fourth, stability refers to the balance's ability to return to its original equilibrium state after being disturbed. If the reading returns to normal once the disturbance is removed, the balance is considered stable. Stability is the most important criterion for evaluating the usability of an electronic balance. Without stability, the balance cannot be trusted for accurate measurements.
