Beams – The three beams on the balance are used to set the level of precision , with each beam working at different increments (1-10 grams, 10 grams and 100 grams). When using the triple beam balance, it is recommended that one start with the lowest level of precision (e.g 100 gram increments).
What are the parts of the triple beam balance?
While the designs of various triple beam balance models differ slightly, they have two basic components in common: the base and the pan . The base is a long metal platform which supports the rest of the apparatus. When moving the triple beam balance, place your hands on either side of the base for stability.
How does a 3 beam balance work?
The triple beam balance is used to measure masses very precisely; the reading error is 0.05 gram. With the pan empty, move the three sliders on the three beams to their leftmost positions, so that the balance reads zero. ... Once the balance has been calibrated, place the object to be measured on the pan.
What is the pointer on a triple beam balance?
Adjustment Knob and Pointer
The pointer is present on the right hand side of the triple beam balance . By default, it points to zero on a labeled scale. Together the pointer and the scale are used to ascertain when the beams are at their resting position and when the correct mass of an object has been found.
How many arms does a triple beam balance have?
For example, the three arms of the triple beam balance are calibrated from 0–100, 0–10, and 0–1.0 grams. First the weight on the 0–100 arm is moved along the beam in 10 gram increments until the increment of weight exceeds the object weight by one unit.
What does a triple beam balance look like?
The Triple Beam Balance is a typical mechanical balance . It has a beam which is supported by a fulcrum. On one side is a pan on which the object is placed. On the other side, the beam is split into three parallel beams , each supporting one weight.
How are the 3 beams on a triple beam balance different?
Its name refers to its three beams, where the middle beam is the largest, the far beam of medium size, and the front beam the smallest . The difference in size of the beams indicates the difference in weights and reading scale that each beam measures.
How do you adjust a triple beam balance?
- First, remove the screw on the side, underneath the pan. This holds the pan in place.
- Next, unscrew the weighing pan to access the weights inside.
- If the weight is too high, remove weight from the inside of the balance. ...
- After the weight is correct, reassemble the balance.
Which rider on the balance should be moved first?
The middle (heaviest) rider should be moved first. This rider measures the largest unit of mass used.
Can you zero a triple beam balance?
Be sure all riders are back to the zero point. Place one hand under the balance and the other hand on the support (arm) to carry the balance. Zeroing: For exact zero, adjust the knurled knob which is located at the left end of the beam.
How do you know if a triple beam balance is zeroed?
For Best Results with a Triple Beam Balance:
Before you weigh something , ‘zero’ the balance. Do this by sliding back all the weight poises (that slide along the beams) so that the pointer is right at the zero line.

Does a triple beam balance measure volume?
In the metric system, we use the following base units: Mass is measured in GRAMS, using a triple beam balance or scale. Volume is measured in LITERS , using a graduated cylinder for liquids. ... Measuring Mass with a Triple-Beam Balance A triple-beam balance has a pan and three beams with sliding masses called riders.
What is the least mass your triple beam balance can measure?
Q: What is the smallest mass this triple beam balance can measure? A: The smallest mass it can measure is one-tenth (0.1) of a gram .
What is the standard mass graduations for the highest beam?
5. A triple beam balance has beams. Each beam has specific standard mass graduations. The highest beam has gram graduations , the second bean has gram graduations, and the third beam has gram graduations with gram graduations in between.
