1  General Information 
1.1  Description 
Thank you for choosing the optris® CT infrared thermometer. 
The sensors of the optris CT series are noncontact infrared temperature sensors. 
They  calculate  the  surface  temperature  based  on  the  emitted  infrared  energy  of  objects  [►9  Basics  of 
Infrared  Thermometry].  The  sensor  housing  of  the  CT  head  is  made  of stainless  steel  (IP65/  NEMA-4 
rating) – the sensor electronics is placed in a separate box made of die casting zinc. 
 
 
The CT sensing head is a sensitive optical system. Please use only the thread for mechanical 
installation. 
 
 
•  Avoid abrupt changes of the ambient temperature. 
•  Avoid mechanical violence on the head – this may destroy the system (expiry of warranty). 
•  If you have any problems or questions, please contact our service department. 
 
 
Read the manual carefully before the initial start-up. The producer reserves the right to change 
the herein described specifications in case of technical advance of the product.
