Thermopen

Thermopen / Temperature Indicating Crayons

 

Thermopen are surface temperature indicating crayons. Thermopens indicate surface temperature by changing from a chalk mark into a liquid smear. It is applied ranging from different temperatures. These crayons are available from 50 degrees to 1000 degrees. However, we can provide with different degree crayons as per customers request.

 

Application

Determining preheat and post heat temperatures during welding, annealing and stress relieving in metal fabrication. Measuring operating temperatures of transformers, motors, glass blowing, steam traps, moulds, electronic components, heat transfer application and hydraulic systems.

General Directions For Use

Remove cap from plastic holder. Push Thermopen slightly out of the holder and retighten with cap. Peel protective aluminium foil to expose Thermopen. Mark the Thermopen on the 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.
