What is the sensitivity of a Class A balance?

The sensitivity of a Class A balance is defined as the smallest weight that can be measured accurately. In pharmacy practice, a Class A balance is primarily used for weighing small quantities of substances. The sensitivity of 6 g indicates that the balance can accurately measure weights of 6 grams or more, ensuring precise formulation of medications and compounds.

This characteristic is vital in pharmacy settings, where precise measurements are essential for maintaining the accuracy and safety of compounded medications. The specification of 6 g means that any weight lower than this may not yield reliable results, making it crucial for technicians to understand the limits of their weighing equipment in order to provide the best patient care and ensure proper medication dosages.

In contrast, other sensitivities listed in the options either exceed this amount or do not correspond to the standard for Class A balances, which is specifically designed for accuracy in small measurement ranges.
