Areas of application for the thermometer optris LS LT

The handheld optris LS LT is perfectly suited for any portable measurement task of non-metallic surfaces. Typical areas of employment for the convenient device are e.g. in preventive maintenance. Since each electricity-driven appliance warms up during an error, defects can be detected reliably and fast.

Of course, the portable laser thermometer is capable of performing every other punctual control process, e.g. in quality assurance, research and development as well as electronic design, in which critical components of machines can be checked for defects. Additionally, detection of thermal bridges on house fronts and in interior rooms poses no problems with the precise handheld thermometer.
