Two-piece Fast Industrial Infrared Pyrometer with Laser-Sighting, -50 °C to 975 °C

The Optris CTlaser Fast LT is a high speed, non contact infrared thermometer with a two piece design, separating the sensor from the electronics for easy installation in tight spaces. It provides fast, accurate, and reliable temperature measurement for demanding industrial applications.

It features a 50:1 optical resolution, a temperature range of -50 °C to 975 °C, and is optimized for non reflective surfaces. With fast response times, dual laser aiming, and standard or close focus optics, it is ideal for plastics, non metals, electronics, and other fast manufacturing processes.

The CTlaser Fast LT supports a wide range of outputs, including 0/4–20 mA, 0–5 V, 0–10 V, USB, RS232, RS485, relay outputs (2), Profibus DP, Modbus RTU/TCP, Profinet, and EtherNet/IP, ensuring easy integration into industrial control systems while delivering reliable measurements for process control and quality assurance.
