Description
Colour-change crayons - irreversible provide a clear visual method for monitoring temperature at 245 °C. Applied as a mark on the surface of interest, the crayon changes colour permanently once the rated temperature is reached and retains that change after cooling, creating an unambiguous record of thermal exposure. This irreversible behaviour is valuable for process control, equipment checks and quality documentation in laboratory and industrial settings where electronic sensors are impractical or a simple threshold indicator is preferred. Each unit is supplied as 1 pc from manufacturer ROTH SELECTION and has a low weight of 0,011 kg, making the crayons convenient to store and use at the bench or on the shop floor. They support verification that components, vessels or assemblies have attained 245 °C during heating cycles, curing steps or other high-temperature operations. Easy to apply on clean surfaces, these temperature-indicator crayons complement conventional measuring instruments and help maintain consistent thermal-process oversight within standard labware and monitoring workflows.
This article is part of Temperature measurement accessories, in Temperature measurement.

Questions about Colour-change crayons - irreversible, for monitoring temperature, 245 °C
What is this article?
Colour-change crayons - irreversible, for monitoring temperature, 245 °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.
