 How
do you determine preheat and post heat temperature during
welding, annealing and stress relieving in metal fabrication?
You cannot measure with thermometres when temperatures
as high as 400 degrees centigrade. In such situations
Thermopens prove useful.
Thermopens are surface temperature indicating crayons.
Thermopens indicate surface temperature by changing a
chalk mark into a liquid smear. Crayon thermopens are
available with pre-indicated temperatures on them like
say, 250, 300, 350, 400 degrees Centigrade, marked on
their surface where the temperature is to be measured.
If the chalk mark turns into a liquid smear then the surface
has attained the rated Thermopen temperature. If the chalk
mark remains unchanged, then the surface temperature is
lower than that rated for the thermopen. Thermopens find
their aplication in measuring operating temperatures of
transformers, motors, glass blowing, steam traps, molds,
electronic components, heat transfer application and hydraulic
systems. They are free of Lead and Sulphur.
Colour changing stickers and crayons are also available.
