Full temperature control and never risk damage again. With the HL Scan, the temperature of the workpiece surface is recorded during processing with the hot air blower. As soon as the ideal temperature is either exceeded or undershot, a signal sounds. In addition, the display shows whether the workpiece surface is too hot or too cold. Red means "too hot", green means "ideal temperature" and blue means "too cold". The HL Scan can be mounted on the HL 1920 E, 2020 E, HG 2120 E and HG 2320 E hot air blowers. The tolerance range for the warning can be set individually. The optical and acoustic warning can be deactivated if required.
