The ink, containing wax, changes colour irreversibly when reaching the temperature at which they are calibrated. This allows to verify if the part or surface has reached the temperature needed in the process because the colour change is permanent.
Temperature pencils are an alternative to adhesive heat-sensitive labels when the temperature to be controlled is higher than 290ºC.
Heat-sensible pencils are available in 3 temperature ranges and, in some cases, they can make more than one colour change:
Supply: Box with 10 units
Dimensions: 7.5 cm long
Type: Irreversible with simple or multiple change depending on the range.
Wax-based pencils with heat-sensitive pigment that makes a simple-type or multiple-type colour change. It should be considered that not only temperature acts in the pigments in these pencils, but also the time of exposure to that temperature. For this reason, procedures should be adapted depending on the time of exposure. Please, contact our technicians if you have any doubt.
If the colour change is produced:
Requirements of use for these pencils to work appropriately:
Accuracy of this product is +/- 5ºC
Made according to ISO 9001 standard.
Temperature pencils meet standard RoHS 3 (EU2015/863), WEE and Reach, with regard to effects to the environment and public health.
Likewise, components in the heat-sensitive pencils are not included in the California Proposition 65 and SVHC lists.
