A double beam balance is a balance comprising of a lever that has two equal arms and a pan suspended from every arm. The pan is where the object to be measured is placed. It also has two beams that have sliding weights to record the measurement.
There are two general types of double beam balance scales. The first is the tabletop kind that is most often seen in laboratories. The second type is more familiar to the general population because it is commonly used in a doctor’s office to determine your weight. Both types have a pan on which the object being measured is placed and two beams with sliding weights to record the measurement. The method for using both types is the same.
Instructions
1        Check the beam to make sure it is balanced with nothing on the scale.
2        Place the object to be weighed on the pan. If you are using a doctor’s scale, stand on the pan. The indicator will move upward.
3        Slide the larger weight along its beam until the indicator points downward. Many scales will have notches for the larger weight. Once the indicator falls, slide the weight back one notch. The indicator should rise again slightly above the center mark.
4        Slide the smaller weight along its beam until the indicator is balanced and points to the center mark. This smaller weight allows greater precision than a single weight on a single beam
5        Read the values indicated on each beam’s scale and combine them to get the object’s or person’s weight.

Mechanical Quadruple beam blance scaleQuadruple Beam Balance Scale. For Laboratory and Educational Use

MB311 Quadruple Beam Balance

  • 311 gram capacity
  • 0.01g readability
  • 1 centigram accuracy
  • Agate bearings for long life
  • 3.5” diameter stainless steel pan
  • Adjustable recessed platform in base can be raised for specific gravity work

This scale has been around for many years.  The quadruple beam design is very popular and is used extensively in schools and laboratories.  This high quality balance is made with stainless steel and aluminum alloy.  These balances are very durable and give better long term service than electronic scales of similar accuracy.

Made of high quality aluminum alloy and stainless steel. Convenient direct beam graduation.

Laboratory Mechanical Quadruple Beam Balance / Physical Balance / Mechanical Balance

Application:
1. The MB311 Single-pan balance is of unequal arm type with 4 beams.
2. The maximum capacity is 311 grams and the readability is 0.01g.
3. It is made of a high quality aluminium alloy, the knife is made of a high quality alloy and the bearing plane is of agate, with a stainless steel weighting pan and includes a buit in platform to aid density determination by weighting samples in air and in water.
4. It is widely used for schools and educational establishments, etc.
5. Adoption of agate knife edge bearing and specially-treated steel knife effectively improve the sensitivity of the balance.
6. Damping device reduces the oscillation frequency during working of the balance, tarring device facilitates weighing of bulk goods, with 210g/610g/310g riders, it facilitates users’ small amount weighing.
