| Records of the maximum temperature the substrate has been exposed to, ensuring the material has been processed. Crayons cover a wide range of temperatures from 248 to 1112°F (120 to 600°C) with an accuracy of ±5°C. Apply to surface being tested—crayons change color within one to two seconds if object is within ±9°F (±5°C) of the temperature rating.
When applied to pre-heated surfaces, should a color change take place, within 1-2 seconds, then the temperature is within +/- 5°C, of it's rating. An instantaneous change indicates the temperature is higher than it's rating, and should a color change take place after 2 seconds then the temperature is below it's rating. Applications: Paper, rubber, textile, plastics, chemical and electrical industries. Zinc foundries, aluminium processing and the glass industry. Iron & steel industry, enamelling, welding and fabricating. 10 Temperatures Crayon Supplied In Kit: Initial Crayon Color: Light Gray: changes to Violet Blue @ 248°F, 120°C Initial Crayon Color: Pink: changes to Blue Violet @383°F, 195°C Initial Crayon Color: Pale Blue: changes to Light Green @419°F, 215°C Initial Crayon Color: Light Purple: changes to Bright Blue @437°F, 225°C Initial Crayon Color: Orange Brown: changes to Black @473°F, 245°C Initial Crayon Color: Yellow Brown: changes to Light Violet @572°F, 300°C Initial Crayon Color: Dark Violet: changes to Red Brown @608°F, 320°C Initial Crayon Color: Aqua Green: changes to White Buff @680°F, 360°C Initial Crayon Color: Red: changes to White @878°F470°C Initial Crayon Color: Apple Green: changes to White @1,112°F, 600°C 10 Pack Individual Range also available - Call! |
