The Optris CTi LThot Infrared Thermometer offers temperature enhanced resistance of the sensing head, allowing operation in ambient temperatures of up to 482°F without additional cooling. This elevated temperature rating makes it suitable for various applications, including dryers, furnaces, heat-treating processes of plastics and textiles processing, and semiconductor production .

The thermometer measures temperatures from -40 to 1922°F with an 8 to 14 µm spectral range. Accuracy is ±1% with ±0.75% repeatability. The stainless steel housing ensures durability in harsh environments .

The adaptability of the series is further emphasized by the range of analog and digital outputs provided by the electronics box, including 0/4-20 mA, 0-5 V, 0-10 V, thermocouple (type K), USB, RS485, RS232 interfaces, relay outputs (2x optically isolated), ProfiNet, Modbus TCP, Modbus RTU, Ethernet TCP, and EtherNet/IP. This adaptability facilitates seamless integration into machinery, enhancing utility across various applications .

Standard cable length is 9.8 ft, with options of 26 ft and 49 ft available. Configuration is supported through CompactConnect or IRmobile software. The unit operates on 8-30 V DC power supply .
