Colour Change Crayon Behaviour
When applied to pre-heated surfaces, if colour change takes
place:
(a) within 1-2 seconds, the temperature is within +/- 5ºC of
its rating
(b) instantly, the temperature is higher than its rating
(c) after two seconds, the temperature is lower than its
rating |
Accuracy: +/-5ºC
