Classification of the Triple Beam Balance Type Chemistry

Basic Triple Beam Balance

• The triple beam balance measures the mass within a 0.05-gram reading error. With the pan empty, the three sliders on the scale are moved to the left position to zero out the balance. When measuring an object or substance, if the indicator drops below a fixed mark, the next slider can be used. To measure the mass of the object or substance, the three numbers on the three beam sliders are added together.

Dial Operating and Magnetic Damping

• The dial operating balances have a convenient direct dial calibration for fine weighing instead of using the sliding scale. In addition, there is a magnetic damping that makes the balance easier and faster to use and gives a more accurate measurement.

Digital Triple Beam Balance

• The digital triple beam balances have built-in calibration and a rear electromagnetic force sensor and output the weights digitally. The user places the object on the scale and the weight automatically appears instead of having to move the sliding scale and balance the object. This type of balance is user friendly and meets the demands for various laboratory analyses.

Triple Beam Balance with Tare

• A triple beam balance with tare has a counterweight to tare up to 225 grams. These usually contain a magnetic damping system to give a more accurate reading. The tare allows the user to place a beaker or container onto the scale before weighing the mass of the liquid or solid substance. The tare then zeros out the scale and the substance can be added; in the older type of triple beam balance, the beaker needed to be measured before weighing and beaker weight was subtracted from the total weight.
