It features an 8.5-inch aluminum case with a lower-mount, 1\/4-inch threaded connection and a bronze Bourdon tube sensing element. The gauge reads from -30 to 0 inches of mercury (Hg), making it suited for monitoring negative-pressure systems. Accuracy is rated at 0.25 percent of scale, providing reliable readings for process monitoring and system diagnostics. Licensed tradespeople, service technicians, and instrumentation professionals typically install and commission this gauge in field or panel-mount settings.\u003c\/p\u003e\u003cp\u003eThis gauge is well suited for residential and commercial mechanical systems where vacuum levels must be monitored continuously or during service procedures. The lower-mount design positions the process connection at the 6 o'clock position, making it a common choice for pipe-mounted or manifold installations where the dial face needs to remain visible from a direct front view. Its large 8.5-inch dial improves readability at a distance, which is useful in equipment rooms and mechanical spaces where gauges are mounted above eye level or across a panel.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e8.5-inch diameter aluminum case for durable, lightweight construction\u003c\/li\u003e\n\u003cli\u003eAnalog dial with vacuum range of -30 to 0 Hg for negative-pressure monitoring\u003c\/li\u003e\n\u003cli\u003e0.25 percent of scale accuracy for precise vacuum readings\u003c\/li\u003e\n\u003cli\u003eBronze Bourdon tube provides corrosion resistance in typical process media\u003c\/li\u003e\n\u003cli\u003eLower-mount, 1\/4-inch threaded connection simplifies inline pipe installation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-install analog vacuum gauge for industrial, HVAC, and mechanical process systems requiring a lower-mount, 1\/4-inch threaded pressure gauge with an 8.5-inch dial.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by a licensed HVAC technician, plumber, or instrumentation mechanic. Isolate and depressurize the system completely before removing or installing the gauge to prevent injury or equipment damage. Use appropriate thread sealant rated for the process media on the 1\/4-inch NPT connection, and do not overtighten, as aluminum cases can crack under excessive torque. Verify that the system vacuum range does not exceed the gauge scale before placing the instrument in service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDial Diameter\u003c\/strong\u003e: 8.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Lower Mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDial Type\u003c\/strong\u003e: Analog\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Range\u003c\/strong\u003e: -30 to 0 Hg\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 0.25 percent of scale\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBourdon Tube Material\u003c\/strong\u003e: Bronze\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCase Material\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 7 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ASHCROFT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 92894\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASHCROFT","offers":[{"title":"Default Title","offer_id":51539128418610,"sku":"92894","price":1546.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/180bb9faa0748d66c7dcfbb71cd71c49_ead18dac-9aee-4ac8-934e-0e71206cd718.jpg?v=1785835054","url":"https:\/\/voomisupply.com\/products\/ashcroft-92894-pressure-gauge-8-5-in-dial-lower-mount","provider":"Voomi Supply","version":"1.0","type":"link"}
