What is a tabletop balance?
Tabletop balance is fast, accurate and portable. This solid and reliable balance is designed to withstand the wear and tear of food service, food processing or harsh environmental conditions. The tabletop balance has a removable, easy to clean, stainless steel weighing pan.
What is the use of weighing balance in laboratory?
Laboratory balances from a general standpoint measure the mass of an object, in the laboratory they are used to measure solids, liquids, tissue, they have a wide range of uses in virtually any laboratory including clinical, research and environmental settings.
Why do we use weighing balance?
A weighing balance is an instrument which is used to determine the weight or mass of an object. Available in a wide range of sizes with multiple weighing capacities they are essential tools in laboratories, commercial kitchens and pharmacies to name but a few.
What is the use of spring balance?
Main uses of spring balances are to weigh heavy loads such as trucks, storage silos, and material carried on a conveyor belt. They are also common in science education as basic accelerators. They are used when the accuracy afforded by other types of scales can be sacrificed for simplicity, cheapness, and robustness.
What does a table top scale measure?
The tabletop scale is a scale for daily laboratory use. Another function besides the normal measuring function of the tabletop scale is the piece counting function. This function allows the tabletop scale to determine the number of screws, for example.
What is the sensitivity of analytical balance?
The rated sensitivity of an analytical balance is that amount of weight which will change the sum of the turning points of the pointer one quarter of one division on the index scale.
What is the principle of weighing balance?
The very basic principle that makes a balance a balance and not a scale is still the same: a counteracting force is created to be compared to the unknown mass. The weighing pan is attached to an electromagnetic coil, through which electric current is flowing. The coil floats in a magnetic field created by an amplifier.
How many types of balance are there?
There are three different types of balance: symmetrical, asymmetrical and radial.
What are the types of weighing balance?
A mechanical scale or balance is used to describe a weighing device that is used to measure the mass, force exertion, tension and resistance of an object without the need of a power supply. Types of mechanical scale include spring scales, hanging scales, triple beam balances and force gauges.
What is the working principle of spring balance?
Hooke’s law
Spring balance is used to determine the force acting on the object (weight). Spring balance works on the principle of Hooke’s law. Hooke’s law states that the strain of the material is proportional to the applied stress within the elastic limit of that material.
What is spring balance for Class 8?
Class 8 Question Spring balance is a device used to measure the weight of small bodies. I t consisits of a spring to hang the weights. As the weigths are hung to the spring it stretches the the pointer indicates the weight hung or the force applied on the spring.
What do you mean by sensitivity of common balance?
Sensitivity of a balance. A balance is said to be sensitive when it can register small differences in weight. The balance beam is most sensitive when its center of gravity lies slightly below its rotation axis.
What are the major types of analytical balance?
The most common types in use today are beam balances, spring balances, top-loading balances, analytical balances, precision scales, and moisture analyzers. Spring balances are the simplest type, consisting of a coiled spring suspended from a fixed point with a pan at the other end.
What are the different types of weighing balance?
Common laboratory balances and scales types are ultra-micro, micro, semi-micro, analytical, and precision balances. The readability of a balance is the smallest difference between two measured values that can be read on the display.
What is the principle of common balance?
Common balance is the balance which has each arm suspended. The unknown mass is placed in one arm and the known mass in another until they both become equal. Therefore this balance works on the principle of moment of weights. When the weights become balanced, equilibrium is attained.
