In contact mode, it measures from 6.0 to 25,000 RPM with an accuracy of plus or minus 0.006 plus or minus 0.5 percent of the reading. In noncontact mode, the range extends to 99,999 RPM with an accuracy of plus or minus 0.4 plus or minus 1 percent of the reading. The unit measures 4.55 inches long by 2.52 inches wide by 1.24 inches thick and runs on three AA batteries, which are included.\u003c\/p\u003e\u003cp\u003eThis tachometer is suited for field diagnostics on motors, fans, blowers, pumps, and rotating equipment found in residential and light commercial HVAC systems, electrical installations, and mechanical service applications. Contact measurement is ideal for accessible shafts and spindles, while noncontact mode allows speed readings on rotating components without direct access. It is compact enough for a tool bag and does not require an external power source.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDual-mode operation: contact and noncontact RPM measurement in one unit\u003c\/li\u003e\n\u003cli\u003eContact range: 6.0 to 25,000 RPM\u003c\/li\u003e\n\u003cli\u003eNoncontact range: 6.0 to 99,999 RPM\u003c\/li\u003e\n\u003cli\u003eContact accuracy: plus or minus 0.006 plus or minus 0.5 percent of digit\u003c\/li\u003e\n\u003cli\u003eNoncontact accuracy: plus or minus 0.4 plus or minus 1 percent of digit\u003c\/li\u003e\n\u003cli\u003ePowered by three AA batteries, included in the package\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for general-purpose rotational speed measurement on motors, fans, blowers, and other rotating machinery encountered in HVAC, electrical, and mechanical service work.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis instrument is a handheld measurement tool, not a permanently installed component. No wiring or mounting is required. When using contact mode, ensure the rotating shaft or surface is accessible and the tip adapter is secure before taking a reading. When using noncontact mode, position the sensor at the manufacturer-recommended standoff distance and apply reflective tape to the target surface if required for accurate readings.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasurement Modes\u003c\/strong\u003e: Contact and Noncontact\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact RPM Range\u003c\/strong\u003e: 6.0 to 25,000 RPM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNoncontact RPM Range\u003c\/strong\u003e: 6.0 to 99,999 RPM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact Accuracy\u003c\/strong\u003e: plus or minus 0.006 plus or minus 0.5 percent of digit (600 to 99,999 RPM)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNoncontact Accuracy\u003c\/strong\u003e: plus or minus 0.4 plus or minus 1 percent of digit (600 to 99,999 RPM)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions\u003c\/strong\u003e: 4.55 inches long x 2.52 inches wide x 1.24 inches thick\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.4 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBattery Type\u003c\/strong\u003e: AA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Batteries\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBatteries Included\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MITUTOYO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 982-552\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MITUTOYO","offers":[{"title":"Default Title","offer_id":51558341476658,"sku":"982-552","price":498.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2d653274836475941240c2ab246a4b45.jpg?v=1786409787","url":"https:\/\/voomisupply.com\/products\/mitutoyo-982-552-contact-noncontact-tachometer","provider":"Voomi Supply","version":"1.0","type":"link"}
