Which description fits the term 'aneroid'?

1. A device using electrical sensors

2. A device for measuring weight

3. A non-liquid based measuring device

4. A device for testing blood sugar

The correct answer is: A non-liquid based measuring device

The term 'aneroid' refers specifically to devices that operate without liquid. In the context of measuring instruments, such as aneroid barometers or manometers, these devices use changes in pressure to provide readings instead of relying on liquid movement. This characteristic distinguishes aneroid devices from other types that may utilize fluids, like mercury barometers. In the given options, a non-liquid based measuring device accurately aligns with the fundamental principle of aneroid technology. By highlighting how aneroid instruments function through mechanical properties rather than relying on liquid mediums, it emphasizes the key aspect that defines them.
