The quartz fiber balance is an extremely simple spring balance, in which a quartz fiber of suitable dimensions is mounted horizontally in a case to protect it from air currents and static charges. Its displacement with microgram or smaller loads is measured by an eyepiece micrometer in a horizontally mounted binocular microscope which is also used for loading and unloading the balance. The precision is approximately 1.0–2.0%; it has a relatively narrow range of 50–100 times its sensitivity; however, balances can be constructed with useful sensitivities which far surpass those of other mechanical balances at present available.
