Pyrometer optris CT P3 for precise temperature measurement of thin plastic film

Due to its special spectral range of 3.43 µm, the pyrometer optris CT P3 is perfectly suited for precise temperature measurements of thin plastic films like PE, PP and PS.

It measures temperatures precisely from 50 °C up to 400 °C and its measuring head offers a temperature resistance of up to 75°C without additional cooling. Its separate electronics box is acclaimed for its easily accessible programming buttons and its illuminated LCD display.


Areas of application for the pyrometer optris CT P3

With a measuring wavelength of 3.43 µm, the infrared thermometer optris CT P3 is ideally suited for temperature control during the production of very thin plastic film. Among those are materials like polyethylene (PE), polypropylene (PP) and polystyrene (PS).
