MONOPLATE or GRANATARY BALANCE: Its Use and Characteristics

Definition of Granataria or Monoplate Scale

A Granataria scale weighs very small quantities and is also used to determine or weigh the mass of some objects and gases. They usually have capacities ranging from 2 to 2.5 kg and measure with an accuracy of up to 0.1 or 0.01 g. In addition, today there are some that can measure up to 100 or 200 g with accuracies of 0.001 g; and on the other hand there are others that can measure up to 25 kg with accuracies of 0.05 g.1.

This scale has the advantage of standing out from all other laboratory scales due to the fact that there are also designs that have the capacity to take much larger measurements than the others, adding to the above that this allows making measurements in a much simpler way and in a very fast and effective way.

Characteristics of Granataria or Monoplate Balance

  • The granataria scale is characterized by being a sensitive scale.
  • Commonly, granataria scales have weighing capacities of around 2-3 kg.
  • The difference in the size of the beams marks the difference in weight and the scale of the reading that each beam has.
  • These weighing devices can be built in different ways, because they can be of double plate or they can be of a single plate.
  • This type of scale must be periodically calibrated each time it is moved from one place to another.

Digital or Electronic Granataria Scale

The electronic scales are characterized because they perform the weighing by procedures involving sensors. These are established as an alternative to the scales of mechanical origin, which has the same task but are based on a set of counterweights.

The electronic scales can have a notorious accuracy and a very reasonable price, this fact is what positions them very well in the market today. The technological advances of the electronics have contributed in simplifying in a considerable way the use of the scales, to diminish the intervals of weighing and to dispense with the specific rooms of weighing.

Electronic scales comprise three fundamental elements:

The transfer mechanism, a measurement transducer and an analog-digital electronic circuit.

Parts or Elements of the Granataria Scale

  • Weights: They establish the comparison of one weight with another.
  • Saucer: This receives the object to be weighed.
  • Index: It is the reference for the calibration.
  • Leveling screw: This screw is used to calibrate the scale.
  • Weight holder: Holds the weights.
  • Base: It holds the instrument.
  • Arm: It is the one that holds the weights.

Granataria Balance or Laboratory Monoplate

The balance is widely used in laboratories as an auxiliary measuring instrument, because, although its precision is lower than that of an analytical balance, it has a greater capacity than the latter and allows measurements to be made more quickly and easily, as well as for its greater operation.

Granataria Balance or Analytical Scale

This scale is built on a symmetrical bar or lever that is supported by a support that has the shape of a blade in a central point called fulcrum. At its ends there are stirrups or bushes that are also supported by blades that allow them to oscillate smoothly. From there, two plates are suspended.

In one, the certified masses or weights are placed and in the other, those that need to be analyzed. The whole set has a locking system that allows the main lever to rest in a stable way when it is not in operation or when the counterweights need to be modified.

It has an external box that protects the scale from interferences, such as air currents, that could occur in the place where it is installed. Currently, an analytical balance is considered to be that which has the capacity to weigh ten thousandths of a gram (0.0001 g) or one hundred thousandths of a gram (0.00001 g); they generally have a capacity of up to 200 grams.

Parts of the Analytical Balance

  • Glass door: They serve to prevent the entry of drafts.
  • Measuring plate: Place where the mass to be weighed is introduced.
  • Current input: For the current input required by the scale for its function.
  • Tare button: This button allows us to return to zeros for a more accurate measurement.
  • Metal Alloy Base: Serves as a support for the balance.
  • 1° Feet to adjust the level: This serves as a base to have leveled the balance.
  • Display: This indicates the weight and other things that have the scale.
  • Button to tare: The use of this button allows us to return to zeros for a more accurate measurement
  • Bubble level: This serves to check or observe in more detail whether the balance is level

Price of the Scale or Scale Granataria or Monoplate

The prices of this type of scale range from 20 Euros or Dollars to 80 Euros or Dollar  depending on the technology and new product updates may change these prices.

Opinions about Which are the Types of Granataria or Monoplate Scales

According to users and experts in scales, these models are among the Granatarias:

  • Triple Bar Granataria Scale with a Capacity of 610 Gr
  • Granataria scale. VE model
  • 4-Arm Granataria Scale. Capacity 310G with DIAL.
  • Digital Granataria Scale 200G
  • Professional Granataria Scale 3000 Gr / 0.01 Gr

How To Use a Scale Granataria or Monoplane ?

The granataria scale is a laboratory scale used to have knowledge of the mass of the objects, they require of certain precision at the moment of knowing the mass of some element. Normally the granataria scales have a capacity to measure between 2 and 2.5 kg with a precision of up to 0.1.

The use of the granataria scale is really simple, since we only have to take an object whose mass is compared with that of another one, in a few words or in other words, counting on a known or established weight we can determine that of another one based on certain comparisons that this scale helps us to make at the moment of using it.

How is the Granataria Scale Calibrated ?

For its correct operation, all scales must be correctly leveled on a rigid surface when using them. The balance must be calibrated continuously and every time it is moved from one place to another. For this purpose, standard masses are used which, in turn, are calibrated with greater precision than the precision of the scale itself.

Cleanliness is a very important factor, therefore, the substances should not be placed directly on the plate of the balance, but on top of the container.

On electronic scales, before weighing the sample, the reading with the container must be set to zero, which is known as taring the scale. This means that the mass of the container does not have to be deducted later.

When carrying out a series of measurements, avoid changing the balance in any way.

To take readings effectively on mechanical scales must avoid at all costs the parallax error, aligning the display accordingly. 1 must be set to zero and place the weight on the plate and move your system until it reaches its required weight.
