Description
Colour-change crayons - irreversible are practical temperature indicators designed for straightforward visual monitoring at 120 °C. Once the marked surface reaches the rated temperature, the crayon mark undergoes a permanent colour change that does not reverse on cooling, giving a clear, lasting record that the threshold has been exceeded. This makes the crayons suitable for process checks, equipment qualification and routine temperature surveillance in laboratory and technical environments where a simple go/no-go indication is required. Supplied as a single piece from manufacturer ROTH SELECTION, each crayon weighs only 0,011 kg and is ready for immediate use on clean, dry surfaces. The irreversible response supports documentation of thermal exposure without electronic instrumentation, complementing other measuring tools in the temperature-monitoring workflow. Ideal for marking components, housings or test pieces that must confirm they have attained 120 °C during heating, sterilisation-related checks or thermal process validation. Compact and easy to handle, these crayons integrate smoothly into existing labware and quality-control routines for reliable, at-a-glance temperature evidence.

Questions about Colour-change crayons - irreversible, for monitoring temperature, 120 °C
What is this article?
Colour-change crayons - irreversible, for monitoring temperature, 120 °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 Instruments de précision.
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.
