Pyrometer optris CT P7 for measurement of foils

Due to its special spectral region of 7.9 µm, the innovative pyrometer optris CT P7 is perfectly suited for temperature measurements of thin plastic materials like PET, PU, PTFE, PA or CTA.

It measures temperatures precisely from 0°C up to 710°C and its measuring head offers a temperature resistance of up to 85°C without additional cooling. The separate electronics box of the foil thermometer is acclaimed for its easily accessible programming buttons and its illuminated LCD display.
