The Steinel® HL temperature scanner measures the temperature at the work piece surface while 
working on it with the Steinel® HL1920E or HG2120E heat gun. 
 
An acoustic signal sounds as soon as heat either exceeds or falls below the ideal temperature. The display also shows whether work piece surface is too hot or too cold. 
 
Red means “too hot”, green means “ideal temperature” and blue means “too cold”. 
 
The HL scanner can be fitted to HL1920E or HG2120E heat guns.
 
The warning tolerance range can be selected to suit individual needs. If chosen, the visual and 
acoustic warning can be deactivated.
