De pyrometer Optris CT LT is uitgerust met een van 's werelds kleinste infrarood sensoren. De sensor heeft een hoge optische resolutie van 22:1. Daarnaast biedt het instrument een grote variabiliteit vanwege selecteerbare analoge uitgangen en meerdere digitale interfaces in de elektronica box.
De uitgebreide versie, de pyrometer Ctex LT, is bovendien uitgerust met een dubbele Zener barrière (voor gebruik in een explosiegevaarlijke omgeving).
