Webster Analytical Balance

The analytical balance operates on the lever equilibrium principle, determining mass by comparing the moment difference between the measured object and standard weights. It is used for weighing samples in laboratories and testing raw material ratios in the coatings and inks industry.
Selection
Select the weighing range based on the sample weight, ensuring that the division value meets the weighing accuracy requirements. Pay attention to environmental vibration and adaptability to temperature and humidity, and check the calibration function. Compare the corrosion resistance of weighing pans made from different materials, and confirm that the data interface matches the recording needs.

A Comprehensive Guide to Selecting an Electronic Balance
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.
