Industrial Pressure Gauge from GNW Instrumentation provides a compact analogue pressure indication point for general industrial equipment, assemblies and plant maintenance work. Its 40mm dial format is appropriate where available space is limited but a clear local pressure reference is still required for inspection, adjustment or routine operator checks.\u003c\/p\u003e\n\n\u003cp\u003eWith a bottom entry connection, this industrial pressure gauge is suited to installations where the gauge is mounted directly above pipework, regulators, manifolds or small equipment connections. This arrangement is commonly preferred on compact machinery and packaged assemblies where the gauge needs to sit in line with the process connection rather than being panel mounted.\u003c\/p\u003e\n\n\u003cp\u003eThe 304 stainless steel case gives the gauge a robust external construction for industrial environments, while brass wetted parts make it relevant for compatible pressure media in general service. The stated 2.5% accuracy supports practical local indication duties where the gauge is used as a visual reference rather than as a precision test instrument.\u003c\/p\u003e\n\n\u003ch2\u003eInstallation and Selection Notes\u003c\/h2\u003e\n\n\u003cp\u003eThis gauge is a practical choice for OEM builds, maintenance replacement and compact plant installations where space, mounting orientation and material compatibility need to be considered together.
