1 General Notes
1.1 Intended use
Thank you for choosing the optris® CTlaser infrared thermometer.
The sensors of the optris CTlaser series are noncontact infrared temperature sensors. They calculate the
surface temperature based on the emitted infrared energy of objects [►8 Basics of Infrared
Thermometry]. An integrated double laser aiming helps to mark the measurement spot on the object
surface. This lies within the two laser points.
The CTlaser 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.

► All accessories can be ordered according to the referred part numbers in brackets [ ].
1.2 Warranty
Each single product passes through a quality process. Nevertheless, if failures occur contact the customer
service at once. The warranty period covers 24 months starting on the delivery date. After the warranty is
expired the manufacturer guarantees additional 6 months warranty for all repaired or substituted product
components. Warranty does not apply to damages, which result from misuse or neglect. The warranty also
expires if you open the product. The manufacturer is not liable for consequential damage or in case of a non-
intended use of the product.
If a failure occurs during the warranty period the product will be replaced, calibrated or repaired without
further charges. The freight costs will be paid by the sender. The manufacturer reserves the right to
exchange components of the product instead of repairing it. If the failure results from misuse or neglect the
user has to pay for the repair. In that case you may ask for a cost estimate beforehand.
1.3 Scope of delivery
CTlaser sensing head with connection cable and electronic box
Mounting nut and mounting bracket (fixed)
Operators manual

1.4 Maintenance
Blow off loose particles using clean compressed air. The lens surface can be cleaned with a soft, humid
tissue (moistened with water) or a lens cleaner (e.g. Purosol or B+W Lens Cleaner).
Never use cleaning compounds which contain solvents (neither for the lens nor for the housing).
