Home Science Tools BS-311S Quad Beam Balance Operating Instructions - page 2
Construction and Application
This quadruple-beam balance is constructed to provide years of reliable,
trouble-free operation. The beam is made of high-quality aluminum alloy
for precise, consistent results. It has a tiered design for better visibility
and faster operation. The agate beam bearings and steel knife-edges
provide high accuracy, repeatability, and durability. The stainless steel
pan provides long life in varied service conditions. The magnetic
dampening system makes the balance faster and easier to use.
This balance is most suitable for high school level science courses,
including physical science, earth science, biology, chemistry, and
physics.
