Liquid Crystal Sheets

Continuous Visual Monitoring of Surface Temperatures from -30°C to 120°C  (-22°F to 248°F)

Telatemp Liquid Crystal Temperature Indicating sheets measure 12"x12" and can be ordered with or without adhesive backing. Standard bandwidth ranges are 20-25°C, 25-30°C, 35-40°C, 40-45°C, and 45-50°C. The entire sheet goes through the reddish/brown to green to blue color span with black visible outside the range of the sheet. Applications include heat transfer studies, energy surveys, flow visualization, infrared beam profiling and fault/short location in electric components and electronic circuits.

Custom requirements are invited.
