Is it illegal to own a triple beam scale?

Cocaine and marijuana are contraband, meaning the possession of it is always illegal. However, a triple beam scale is a legitimate subject of private ownership and is not contraband.

How do you do a triple beam balance?

To use a triple beam balance, place an object on the pan and adjust the counterweights until the pointer is balanced at the zero line. Then determine the mass by looking at the position of each counterweight. Add the masses given by each counterweight to find the total mass of the object.

What are the increments on a triple beam balance?

Typically, the reading scale of the middle beam reads in 100 gram increments, the far beam in 10 gram increments, and the front beam can read from 0 to 10 grams. The triple beam balance can be used to measure mass directly from the objects, find mass by difference for liquid, and measure out substances.

What is an example of a triple beam balance?

For example, if the middle slider is in the 200-gram notch, the rear slider is in the 10-gram notch and the front slider is halfway between the 2-gram and 3-gram notches, you would total 200 grams plus 10 grams plus 2.5 to get 212.5 grams. The total of the three numbers is the weight of the object.

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.

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.

Can a triple beam balance measure volume?

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.

How do you measure mass using a triple beam balance?

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. A triple-beam balance gets its name because it has three beams that allow you to move known masses along the beam.

What does it mean to zero a triple beam balance?

Tare (or taring) the weighing container. This means weighing the empty container so that its weight can be deducted from the weight of the sample you want to weigh. (Some balances, but not these triple beam ones, allow you to “zero” the balance with the empty weighing container on them.

How are three beams on a triple beam balance different?

Beams and Riders. As implied by the its name, there are three different beams on the triple beam balance which function independently to asses the mass of an object. Located on each beam is a weighted rider which you slide along the beam to determine the object’s mass.
