The wonderfully designed Masterkidz Double Pan Balance features some clever design elements to make it easy and accurate to use. When set up, the pointer should hang down vertically. To achieve this, trimming weights are located at the far ends of the beam arms. Additionally, a spirit level bubble is used to confirm that the beam is precisely horizontal.
 
Once set, the pointer will be in the perfect position to measure the mass of an object precisely. To do this, an object is placed onto one pan, tipping the balance arm to one side. Then, the known weights (which come with the set) are placed onto the other pan until the pointer returns to the vertical position.
 
Additionally, children can place different weight combinations onto the balance pans to achieve perfect balance—a super and invaluable science and maths resource.
