This image displays a three-panel vacuum gauge measurement instrument labeled A133-5. The device consists of three vertically stacked chambers, each containing an analog dial gauge with measurement scales and a corresponding control lever or valve mechanism. Each chamber appears to be identical in design and construction, featuring cream-colored panels mounted within a brushed metal frame with securing fasteners. The label visible on the middle chamber indicates "AIR" in yellow highlighting. The device is mounted against a textured concrete or stone wall surface. The overall configuration suggests this is laboratory or industrial testing equipment designed for measuring vacuum levels across multiple independent chambers or test points simultaneously.
