Analytical balances are highly sensitive lab instruments designed to accurately measure mass. Their readability has a range between 0.1mg - 0.01mg. If you need more accurate readings we recommend a micro balance
. Analytical balances come with a draft shield or weighing chamber to prevent the very small samples from being affected by air currents. They're meant to detect very fine increments, so the slightest vibrations or breeze can easily impact the results. To counteract this, analytical balances should be used in a dedicated room with as few disturbances as possible. Calibration needs to be done frequently to ensure best results. Most analytical balances have both automatic internal motorized calibration and calibration with external weights.
