Selecting Scales & Balances on Amazon.com
Lab scales are used in laboratory, research, and educational applications to measure object weight; while a balance is used to determine the mass of an object relative to a defined standard. Measurement results from a balance are generally considered more precise than results from a scale.
An analytical balance measures to a high degree of precision and accuracy, and displays results digitally. A moisture balance uses heat to analyze moisture content in a sample. A conventional balance is less precise than an analytical balance and is commonly used in offices, the jewelry industry, and in kitchens. A mechanical balance is the simplest type of balance, and uses a lever and slide to indicate measurement. A spring scale is a type of lab scale that is commonly used for general weighing purposes and in classrooms for force and action-reaction demonstrations. Manufacturers include Mettler-Toledo, Ohaus, and Sartorius.
