This enclosure is often called a draft shield.

Double pan balance function.

An analytical balance or lab balance is a class of balance designed to measure small mass in the sub milligram range. The balance also balance scale beam balance and laboratory balance was the first mass measuring instrument invented. C quackenbush 21 250 views. Triple beam balances work on the same principle as the classic double pan balance you probably first think of when hearing the word balance.

2019 the jim henson company. These weights feature flat countersunk bottoms with a double ended hooked rod through the middle. The triple beam balance is a measuring instrument comprising a beam supported on a fulcrum. Norman price recommended for you.

This video demonstrates how to use a double pan mass balance. 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 parts of a double pan balance are the two weighing pans the pointer rider or sliding mass and rider arm. They can be used on balance pans as well as hooked in tandem for lever arm studies. This scale can be used to determine the mass of an object. The amount of beams doesn t change the way the balance works they just add increments which in turn improves the precision.

A top pan or top loading balance is an instrument used to weigh solid materials when perfectly accurate measurements aren t necessary. How to use a double pan or equal arm balance duration.

In its traditional form it consists of a pivoted horizontal lever with arms of equal length the beam and a weighing pan 7 suspended from each arm hence the plural name scales for a weighing instrument.
