Manual Balance

Manual balances are based on the principle of lever equilibrium, where the beam is leveled by adjusting the sliding weight and adding or removing counterweights. They are used in laboratories to weigh solid powders, granules, and other materials. During operation, items should be handled gently to avoid vibrations that could affect readings. These balances are suitable for routine mass measurements and formulation preparations.
Selection
When selecting a manual balance, it is essential to consider a weighing range that covers the sample weight, a division value that meets precision requirements, and corrosion-resistant materials suitable for the laboratory environment. Additionally, inspect the wear level of the knife edge and the sensitivity of the beam, ensure stable balance under no load, and regularly calibrate the weights.

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.
