Micro balances are a highly precise scale with a typical readability out to 0.002 mg or 0.001 mg. They are specifically used in high requirement laboratories with entirely controlled environments. With the level of readability and accuracy of a micro balance, even the slightest irritation or disturbance to the environment could cause the balance to give inaccurate readings. For more information about micro balances, their uses, and how to properly operate, please contact us at Scales Plus. We are always happy to help!
