Overview
MW82510 is a 52 mm Bourdon tube mechanical turbo boost gauge. It displays both vacuum (inHg) and positive pressure (psi) on a single scale through a Bourdon tube and gear mechanism, measuring turbocharger boost pressure. Intended for boost monitoring on turbocharged diesel and gasoline engines, aftermarket replacement, and OEM / ODM applications.
Full-scale range 0–30 inHg / 0–30 psi (combined vacuum-boost scale), ±3% full-scale accuracy, compliant with JIS D5603 and JIS D0204; storage temperature per SAE J1810. Automotive-grade -40°C to +85°C operating temperature, IP67 front-side ingress protection.
