IR thermometer optris CTlaser G7 for temperature measurement of glass surfaces

The infrared thermometer optris CTlaser G7 is perfectly suited for precise temperature measurement of ultra-thin glass surfaces. It offers a broad temperature range from 100 °C up to 1200 °C and can be employed in temperatures of up to 85°C without additional cooling.

The IR thermometer for measurements of plastic foils and glass temperatures is capable of targeting smallest objects of 1.6 mm (0.06 in) in a distance of 70 mm (2.76 in). Its standardized two-wire interface additionally allows for a reliable transfer of measurement data and easy integration into a PLC.
