The Optris CTex infrared thermometer is a two piece measuring system with an active electronic for evaluation and an IR sensing head that can be installed as a passive element in hazardous areas. It is encased in aluminum housing with mounting appliances for two zener barriers and CT electronics.

Selectable analog outputs and multiple digital interfaces offer high variability. Field selectable analog outputs options include: 0/4-20mA, 0-10 V, and type K or J thermocouples. The Optris CTex features peak hold, valley hold, average, and an extended hold function with threshold and hysteresis. It also includes a programmable functional input for external emissivity setting, ambient temperature compensation, and reset of hold functions.

The Optris Compact Connect temperature analysis software is available as a free download, and is necessary to document and analyze temperature measurement data. It is compatible with all netbooks, notebooks, and PC systems via Windows XP, Windows Vista, Windows 7 and 8.
