Double Beam Balance
Product Code : EL-B-10740
Quick answer: The Double Beam Balance is a two-pan mechanical balance with two graduated beams, reading to 0.1 g over a 210 g beam range and weighing up to 2 kg with supplementary masses. It is used for fast comparative and general weighing in science practicals, helped by magnetic damping and a spring-loaded zero adjuster. Lab Exports manufactures it in Delhi for school and college laboratories.

How the double beam balance is used
The balance combines two ways of weighing. Up to 210 g the object is balanced with the sliding masses on the two graduated beams: one beam covers 0 to 200 g in 10 g steps and the other 0 to 10 g in 0.1 g steps. For heavier loads, supplementary masses are placed on the other pan and the beams make up the remainder, taking the capacity to 2 kg.
Magnetic damping slows the swing of the beam so the pointer settles quickly, and the spring-loaded zero adjuster corrects the empty reading without moving the sliders. The 150 mm stainless steel pans take beakers and larger samples, which suits weighing soil, water and chemical samples in class.
- Set both sliders to zero and use the spring-loaded zero adjuster until the pointer is at the centre.
- Put the sample on the left pan.
- Move the 10 g slider along its beam to the last position before the pointer passes the centre.
- Slide the 0.1 g mass along the second beam until the pointer rests at the centre.
- For loads above 210 g, add supplementary masses to the right pan first, finish with the beams, and add everything together.
