The Optris CT LT infrared temperature sensor has one of the smallest infrared sensors available, and an optical resolution of 2:1, 15:1, or 22:1. Close focus optics can be pre-installed as either 0.6mm at 10mm (LT22) and 0.8mm at 10mm (LT15). The CT LT can function in ambient temperatures up to 356°F (180°C) without additional cooling.

Selectable analog outputs and multiple digital interfaces offer high variability. Field selectable analog output options include 0/4-20mA, 0-5, and 0-10 V, and type K or J thermocouples. The Optris CT LT includes a programmable functional input for setting external emissivity, ambient temperature compensation, and reset of hold functions. It also features peak hold, valley hold, average, and an extended hold function with threshold and hysteresis. USB, RS485, RS232 interface, 2 optically isolated relay outputs, CAN-Bus, Profibus DP, and Ethernet available with plug-in options.

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.

Temperature analysis software for simple and fast parameterization of compact and high performance fixed IR thermometers.
