Compact Two-piece Industrial Infrared for fast temperature measurement, -50-1050°C

The Optris CTi LTfast pyrometer is designed for fast and accurate non-contact temperature measurement, featuring an extremely short response time of 6 ms, making it ideal for rapid control loop applications and demanding industrial processes. Its smart data processing, fast analog output, and instant digital communication ensure reliable and precise temperature monitoring.

Featuring one of the world’s smallest infrared sensing heads and optical resolution up to 25:1, the CTi LTfast series provides excellent measurement performance, even on low-temperature, high-emissivity targets. Its robust design allows operation in ambient temperatures up to 125 °C without additional cooling, making it suitable for challenging industrial environments.

With a wide temperature range from -50 °C to 1050 °C and multiple communication options including USB, RS485, RS232, Ethernet, Modbus, Profinet, EtherNet/IP, IO-Link, and EtherCAT, the CTi LTfast offers flexible integration into various systems. Manufactured in Germany, its durable stainless-steel housing, fixed installation design, and optional accessories ensure long-term reliability and adaptability across a wide range of applications.
