Double Beam Balances weigh a sample by balancing two pans on a central pivot. This mechanical physical balance needs no power supply and shows students how mass comparison works. Sliding riders on two beams set the weight. The first beam moves in 0.1 g steps, and the second moves in 10 g steps. With loose weights added, the balance reaches 2000 g at 0.1 g readability. Magnetic damping settles the pointer in seconds. A 150 mm stainless steel pan resists chemical spills and wipes clean easily. Typical uses include school and college physics and chemistry labs, density experiments, pharmaceutical compounding, food ingredient weighing and microbiology media preparation.
