    Temperature Crayon Assortments

    Image of Product. Front orientation. Temperature Crayons. Temperature Crayon Assortments.
    Apply multiple temperature markings to workpieces, pipes, and equipment to monitor a wide range of temperature changes. Marks melt when the surface reaches the rated temperature, giving you quick, no-instrument confirmation during welding preheat, stress relieving, and heat treatment. Assortments let you verify temperature progression across a range in a single pass, confirming a surface has reached but not exceeded critical thresholds. All come in a plastic case.
