It measures 0 to 60 inches of water (0–60 inH2O) via a lower 1\/4\" NPT male connection (02L). The 'AS' suffix denotes the stainless steel bellows option, while the '02L' code indicates the connection size and location. Designed for dry-dial operation in pressure ranges typical for HVAC and instrumentation, this gauge is suitable for monitoring small differential pressures in air and non-corrosive gas lines and is commonly panel-mounted or surface-mounted in control panels and mechanical rooms. The 4-1\/2-inch diameter offers clear, easy-to-read readings from a distance, and the instrument is part of Ashcroft's 1188 family of gauges known for reliability in low-pressure service. Optional enhancements such as traceable calibration certificates (C4) or oxygen-service-ready configurations can be specified according to Ashcroft datasheet guidelines. \u003c\/p\u003e\u003c\/div\u003e","brand":"ASHCROFT","offers":[{"title":"New","offer_id":51660283117870,"sku":null,"price":217.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_ae8785ed-2d50-4ab0-8043-fdab2c6dff12.jpg?v=1769535566","url":"https:\/\/plgautomation.com\/products\/ashcroft-451188as-02l-general-service-gauge-four-and-one-half-inch","provider":"PLG Automation ","version":"1.0","type":"link"}
