INFRARED THERMOGRAPHY (IR)

Infrared Thermography inspection testing is essentially a non-invasive, non-destructive inspection process that uses temperature sensing scanners.

Infrared testing is used to locate and document thermal anomalies (hot spots).

These infrared devices gather temperature signatures that lie beyond the range of visible light. Analysis of this data will help you detect a wide range of problems in building systems and structures, including moisture intrusion, missing or damaged insulation, overloaded circuits, faulty wiring, loose electrical connections and construction defects and also to identify other potentially dangerous situations which can in turn cause failure and downtime of plant and equipment.

POSITIVE MATERIAL IDENTIFICATION (PMI)

Positive Material Identification (PMI) is the identification and chemical analysis of various metal alloys through nondestructive methods. 

 PMI is employed for the following:

• when a sample cannot be cut for routine testing,

• when a mixed lot is suspected,

• when material identification/documentation has been misplaced,

NDTL performs these checks by use of portable handheld units.
