The Ashcroft acid leak detection (ALD) assembly provides multiple layers of safety when dealing with acid media. The ALD product combines a pressure gauge and a diaphragm seal into a single assembly, welded together at the socket. The assembly is gauge welded to seal standard. The diaphragm seal, gauge socket, and portions of the gauge case are coated with a yellow, acid-detection material that turns red when exposed to leaking acid with a pH ≤ 3.0. The lower portion of the gauge is also coated with ALD to indicate any leakage in the bourdon tape or welded joints of the gauge system.
