Electronic balance - An electronic balance is an automated balance based on the principle of generation of current that is proportional to the displacement of the pan. An analytical balance scale, often called a "lab balance", permits quantitative analysis of a sample. Typical applications of an electronic analytical balance include: To start a weighing operation, open the door and place a container on the pan using gloves or tweezers. We would like to let you know that some features on the site may not be available or may not work as nicely as they would on a newer browser version. The quickest way to understand the principle of how electronic balances work, is to first understand how they are constructed. Before using a triple beam balance, the scale pointer should be at zero. Spring balances are the simplest type, consisting of a coiled spring suspended from a fixed point with a pan at the other end. The calibration applies for the current ambient temperature. A balance should not be located near hot or cold objects, such as cold windows, radiators, electric ovens, stills, or areas that are at a different temperature than the rest of the room. Reliable analytical results begin with accurate weighing. Intuitive operation and integrated applications make your weighing process fast and convenient. Electronic Analytical Balance: Stabilization Time ≤1.5 sec. | What is the analytical balance minimum weight?
