Optris CSlaser LT Dual-Laser Infrared Thermometer | -30–1000 ℃, D:S 50:1, ±1 ℃ or ±1%, 4-20 mA/USB, IP65

Optris CSlaser LT Dual-Laser Infrared Thermometer: 50:1, -30–1000 ℃

Overview

The CSlaser LT is an Optris compact fixed infrared thermometer. Two laser beams follow the infrared optical path to mark the actual measurement spot, converging into a single point at the focus. It operates at ambient temperatures up to 85 ℃ without additional cooling. Output options are 4-20 mA analog, programmable alarm or USB, and PC software can be used to set emissivity and record temperature trends. Close-focus optics versions for smaller targets are available on request.
