Triple Beam Balance Function
- Keeping the pan empty, move all three riders on the three beams to their leftmost positions. Check the pointer and scale to ensure that it reads zero.
- After calibration, place the object to be measured on the center of the pan. The pointer will move away from the zero reading.
- Slide the 100 gm rider to the left slowly from notch to notch, until the pointer drops below the zero mark.
- Now move the 10 gm rider from notch to notch in a similar manner as you did with the 100 gm notch until the pointer drops below zero ...
- Lastly move the 1 gm rider slowly on its beam until the pointer aligns at zero. ...
- Take the total of all the three numbers indicated by the positions of the three riders to get the mass of the object on the pan.
What are the measurements on a triple beam balance?
The maximum weight a triple beam balance can measure is 600 grams. The first beam can measure up to 10 grams. The second beam can measure up to 500 grams, read in 100 g increments. The third beam can measure up to 100 grams, read in 10 g increments. Each beam has notches (e.g., grooves) for the weights.
What are the steps for using a triple beam balance?
- The first beam can measure up to 10 grams.
- The second beam can measure up to 500 grams, read in 100 g increments.
- The third beam can measure up to 100 grams, read in 10 g increments.
What is a triple beam balance and how is it used?
The triple beam balance is an instrument used to measure mass very precisely. The device has reading error of +/- 0.05 gram. The name refers to the three beams including the middle beam which is the largest size, the front beam which is the medium size, and the far beam which is the smallest size.
Does a triple beam balance measure mass or weight?
Scientists need balances that can measure very small amounts of mass. Because a triple beam balance compares a known mass to an unknown mass it is unaffected by gravity. Unlike a spring scale which really measures weight, the triple beam balance gives a true measure of mass.

Next place the object on the pan.
What is the first step when using a triple beam balance?
What is the first step when using a Triple-Beam Balance? 1. First, zero or calibrate the balance. It is zeroed if the pointer is at the zero when the pan is empty, and the riders are all the way to the left on the beams.
How do you balance an object on a triple beam balance?
Move each slider on the three beams to the far left so the pointer is straight and aligned with the central mark on the balance. Place the object you want to weigh on the balance's pan and allow a few seconds for the balance to settle. The pointer will now be above the central mark.
How do you use a beam scale?
How to Use a Physician Beam ScaleRemove your shoes and any heavy clothing such as a jacket before stepping on the scale. ... Step onto the scale facing the beam. ... Slide the small weight slowly along the scale. ... Determine your actual weight once the beam comes to rest in a straight line horizontally.

You need to decrease the amount of weight on the scale.MoreIf the balance bar is touching the bottom. You need to decrease the amount of weight on the scale. Remember the goal is for the balance bar to float in the center of the balance.
How does a balance beam scale work?
Beam balances use an application of the lever principle. Something called a fulcrum is placed between the force exerted by the counterweights and the load. The lever principle states that "the further away the counterweight is from the fulcrum, the more downward force it exerts".
What is triple beam balance scale?
The triple beam balance is an instrument used to measure mass very precisely. Such devices typically have a reading error of ±0.05 grams. 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.
What is the triple beam balance?
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.
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.
What is a triple beam balance scale?
Triple beam balance scales function by balancing an object with three counterweights that are attached to the scale to accurately measure the object's weight.
How to calibrate a weight scale?
Calibrate the scale by sliding all three weight poises (the metal brackets that slide along the three beams) to their leftmost positions. Twist the zeroing screw (usually located below the pan in which you place the object to be weighed) until the balance pointer lines up with the fixed zero mark. Place the object to be weighed on the center ...
Can you zero out the scale before using the triple beam balance?
Failing to zero out the scale before using the triple beam balance can result in inaccurate measurements.
How much weight can a triple beam balance measure?
When all three riders are positioned completely to the right, their combined weight equals 500 gm + 100 gm + 10 gm = 600 gm. This is the maximum weight that the triple beam balance can measure.
What is triple beam balance?
The triple beam balance is a measuring instrument comprising a beam supported on a fulcrum. On one side of this beam, is a pan on which the object to be measured is placed, while on the other side, the beam is split into three parallel beams, each carrying a known weight and together culminating into a pointer pointing to a fixed scale. The weights are slid on their respective beams until zero reading is obtained and a state of balance is achieved.
How many beams are in a triple beam balance?
As the name of this apparatus implies, the triple beam balance comprises three beams which are individually used to determine the mass of an object. Each of these three beams has a weighted rider on it, which the user can slide along the length of the beam to determine the object’s mass. When positioned such that the pan is on the left hand side and the scale and pointer to the right, the beam which is located on the front has a 10 gm scale and a 0.1 gm rider on it.
What is the metal platform on a triple beam balance?
The solid metal platform which supports the rest of the parts of the triple beam balance is known as the base. It provides stability to the apparatus while the measurements are being taken. The pan is located on one side of the apparatus and rests on top of the base. It is where the object to be weighed is placed.
What is a Triple Beam Balance?
Triple beam balances are a type of lab equipment. The purpose of the balance is to measure the mass (how much stuff is inside something) of an object that is placed on the pan (flat stainless steel surface). Generally, the object which is being measured has a small mass as the balance does not exceed 610 grams.
Triple Beam Balance Parts
Base: The base of the balance is what holds all the parts in place. It is located at the bottom of the balance and rests on a flat surface.
What is a Triple Beam Balance Used for?
A triple beam balance measures the mass of an object with a mass less than 610 grams. Observe a triple beam balance and the three different beams. Based on the diagram provided in this lesson, the beam's measurement is front to back: the beam in the front is 10 g (grams), the middle is 500 g (grams), and the beam in the back is 100 g (grams).
