Level II Infrared Thermography Course A Certified Infrared Thermographer Level II Application Course

Level II Certified Infrared Thermographer® is a five-day course for the application of quantitative thermal imaging and temperature measurement for P/PM, Condition Monitoring, Quality Assurance, and Forensic Investigations.

This course covers advanced infrared theory, equipment calibration, error sources, cross-verification with contact thermometers, advanced equipment operation, use of windows and filters, assigning temperature limits and repair priorities, and quantitative report generation.

Infraspection Institute is recognized by the Society for Maintenance & Reliability Professionals (SMRP) as an approved provider of continuing education and training aligned with key subject areas related to reliability and physical asset management.

Students are encouraged to bring their own imager for individualized training or to learn how to use it more effectively.

Course tuition includes all course presentations, Student Reference Manual, and Infraspection Institute Certified Infrared Thermographer® exam. Certification card and diploma issued with passing grade of 80%.

This course is eligible for 35.5 NETA Continuing Technical Development Credits (CTDs). NETA Certified Technicians (Level III and Level IV) are required to earn a minimum of 48 CTDs every three years to maintain their certification.

Course is approved by the InterNational Association of Certified Home Inspectors for 32 hours of continuing education and meets the training requirements for their Infrared Certified professional designation and logo.

Course completion and passing grade on certification exam qualify for 20 points toward initial membership in the Infraspection Institute Master Thermographer® program.
