  • Page 8: 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].

  • Page 9: Warranty

    ► 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.

  • Page 10: Maintenance

    General Notes 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). 1.800.561.8187 information@itm.com www.
