Morphology
The meaning is directly and transparently derived from combining 'vacuum' (an empty space lacking air) with 'gauge' (a device that measures), so a B1 learner who knows both constituents can infer it denotes an instrument for measuring vacuum/low pressure. The noun–noun compounding pattern for naming measuring instruments is common cross-linguistically, making the overall sense predictable despite the technical detail about pressure below atmospheric.
Etymology
The noun vacuum gauge comes from early glass or metal instruments where a scale or pointer showed how much air had been taken out; vacuum means 'empty space with no air' and gauge means 'a tool with a scale'. So, vacuum gauge now means 'a device that shows how strong the vacuum is'.
