The crayon marks a surface and melts visibly and instantly when the material reaches exactly 194 degrees F (90 degrees C), providing an immediate, calibration-free visual confirmation. Accuracy is rated within plus or minus 1 percent of the Fahrenheit rating and plus or minus 3 percent Celsius. The bullet-tip format allows precise application to workpiece surfaces before or during heating. HVAC techs, pipefitters, welders, and plumbers rely on Tempilstik crayons to confirm preheat and interpass temperatures without the need for contact thermometers or pyrometers.\u003c\/p\u003e\n\u003cp\u003eThe TEMPIL 28308 is suited for use on aluminum, ceramic, glass, iron, plastic, stainless steel, and carbon steel surfaces. It is commonly applied in HVAC brazing operations, pipe welding preheat verification, and industrial heat treatment quality control. The single-stick format makes it easy to carry in a tool bag or toolbox for field use. It is available as part of a broader Tempilstik range covering 116 temperature ratings from 100 degrees F (38 degrees C) to 2000 degrees F (1093 degrees C), allowing technicians to select the exact threshold needed for a given process specification.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMelts instantly at 194 degrees F (90 degrees C) for immediate visual confirmation\u003c\/li\u003e\n  \u003cli\u003eCalibration-free operation with accuracy within plus or minus 1 percent Fahrenheit\u003c\/li\u003e\n  \u003cli\u003eBullet tip for precise surface marking before and during heating\u003c\/li\u003e\n  \u003cli\u003eCompatible with aluminum, ceramic, glass, iron, plastic, stainless steel, and steel\u003c\/li\u003e\n  \u003cli\u003ePart of a 116-temperature Tempilstik range from 100 degrees F to 2000 degrees F\u003c\/li\u003e\n  \u003cli\u003eCompact single-stick format suitable for field and shop use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on aluminum, ceramic, glass, iron, plastic, stainless steel, and steel surfaces in welding, brazing, heat treating, and related thermal applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eApplied by welders, pipefitters, HVAC technicians, and heat treatment personnel before or during heating operations. Mark the workpiece surface near the area of interest prior to applying heat; the mark will liquefy and spread when the surface reaches the rated temperature. No tools or power source are required. Store away from heat sources and direct sunlight to prevent premature softening of the crayon tip.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Temperature Indicating Crayon\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTemperature Rating\u003c\/strong\u003e: 194 degrees F (90 degrees C)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTip Shape\u003c\/strong\u003e: Bullet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Materials\u003c\/strong\u003e: Aluminum, Ceramic, Glass, Iron, Plastic, Stainless Steel, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: Plus or minus 1 percent Fahrenheit, plus or minus 3 percent Celsius\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAvailable Range (Tempilstik Line)\u003c\/strong\u003e: 100 degrees F (38 degrees C) to 2000 degrees F (1093 degrees C)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 55121731\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: TEMPIL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 28308\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TEMPIL","offers":[{"title":"Default Title","offer_id":51543584702770,"sku":"28308","price":24.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3fd9f0d7ceac055a17198e7a4dc6ccf7_7d2b8cbe-94e2-4a73-b218-831d03d44c2e.jpg?v=1785920707","url":"https:\/\/voomisupply.com\/products\/tempil-28308-temperature-indicating-crayon-194f","provider":"Voomi Supply","version":"1.0","type":"link"}
