It is mostly used by chemistry and physics teachers to demonstrate how mass of any object or material, often How to carry out titration experiment is usually taught in the same manner. Is been measured accurately. The triple balance functions with three counter weights attached to the scale. This is to accurately find the weight of any object.
You must have been familiar with a balance. A balance is usually recommended for chemistry and physics courses, frequently to be used for weighing out small amounts of chemicals to use in solutions. To get you started on easy and efficient use of your triple beam balance, here are a few suggestions

Before you weigh something, 'zero' the balance. Do these by sliding back all the weight poises (that slide along the beams) so that the pointer is right at the zero line. You might need to turn the zero adjustment knob a little bit to get it right at the line.

zero' the balance.
When you set an object on the balance platform, the pointer immediately goes up and is no longer zeroed. To find out the weight of the object, you'll need to slide the weight poises until the pointer is at zero again. Start with the two heavier weight poises and then use the lightest one to do the fine tuning
