WILLIAMSON CORP.

On-line infrared thermometers provide noncontact temperature measurement of thin plastic films, other plastic extrudates, coatings, and molded parts.

Difficult temperature measurements, such as on tenter frames for extremely thin films, use thermometers employing precise narrow-band infrared filters. This technique enables the device to measure the surface temperature of film without looking through the film or being influenced by the background.

Monitoring and controlling temperatures during heating in infrared or hot-air ovens is possible by measuring product temperature itself, rather than measuring air or heater temperatures.
