Description
Colour-change crayons - irreversible are temperature-monitoring crayons intended for irreversible indication at 600 °C. Once the marked surface reaches the rated temperature, the colour change remains after cooling, giving a permanent visual record that the threshold has been attained. This makes the crayons practical for process control, heat-treatment checks, furnace work, and equipment validation where continuous observation is not feasible. The single-piece pack (1 pc) weighs 0,011 kg and is compact enough for targeted marking at individual monitoring points on components, vessels, or fixtures. Applied directly to the surface under test, the crayon leaves a clear mark that laboratory and industrial users can inspect after the thermal cycle. Positioned within temperature indicators and measuring instruments, these irreversible crayons from manufacturer ROTH SELECTION support quality assurance workflows that require simple, non-electronic confirmation of temperature exposure. They complement other labware used for thermal monitoring without relying on power, data logging, or complex instrumentation, and suit routine checks in research, production, and maintenance environments.

Questions about Colour-change crayons - irreversible, for monitoring temperature, 600 °C
What is this article?
Colour-change crayons - irreversible, for monitoring temperature, 600 °C is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Temperature measurement accessories, inside Temperature measurement, in Lab instruments.
These are the connectors, the wells and the spare probes that complete a thermometer or a logger. A thermocouple connector of the wrong type silently adds an error. The accessory has to be the same sensor family as the meter.
A thermometer reports a temperature. A liquid-in-glass thermometer is a calibrated column. A digital thermometer is a sensor and a display, and the sensor, not the display, is what is calibrated. An infrared thermometer reads a surface and depends on emissivity. A data logger stores the reading over time. Without a stated uncertainty and a calibration point, the number is only an indication. The scale is maintained by the BIPM and compared by EURAMET. Accreditation is BELAC.
