It provides direct-reading depth measurements via a calibrated dial face, allowing technicians to quickly verify dimensions without calculation. The gauge is a hand tool designed for use in fabrication, maintenance, and inspection settings where accurate depth measurement is required. At 0.98 pounds, it is lightweight enough for bench or field use. Trade professionals including machinists, pipefitters, and maintenance technicians rely on this type of instrument for quality control and layout work.\u003c\/p\u003e\u003cp\u003eThe TZ 2\/30 is suited for industrial and commercial applications where precise depth measurement is part of standard workflow. Typical use cases include measuring counterbore depth, checking groove dimensions, and verifying recess depth on machined components. It is appropriate for shop floor inspection, maintenance shops, and light fabrication environments. The dial readout format makes it accessible for technicians who need repeatable measurements without electronic instrumentation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDial face provides direct depth readings without manual calculation\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.98 pounds, suitable for bench or field use\u003c\/li\u003e\n\u003cli\u003eMeasures depth of holes, slots, recesses, and stepped surfaces\u003c\/li\u003e\n\u003cli\u003eIndividual unit packaging with a minimum order quantity of one\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose dial depth gauge for use in standard machining, fabrication, and maintenance inspection applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eDial depth gauges require no installation but should be handled and stored carefully to maintain calibration accuracy. Zero the gauge on a known flat reference surface before taking measurements. Protect the dial mechanism and probe tip from impact and debris. Calibration should be verified periodically against a certified gauge block or reference standard per applicable quality procedures.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.98 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: TZ 2\/30\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51710987305266,"sku":"TZ 2\/30","price":678.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c030d48abc9f3f5f70c05e9765314707.jpg?v=1788473212","url":"https:\/\/voomisupply.com\/products\/spi-tz-2-30-dial-depth-gauge","provider":"Voomi Supply","version":"1.0","type":"link"}
