DeltaTherm is remarkably fast. The detector array contains thousands of on-chip integrators which collect data simultaneously, producing a near-live full-field stress image.

The high-speed digital electronics correlate load and stress induced temperature changes for immediate video presentation of stress patterns.


When portability is required, DeltaTherm's small size and light weight make set up quick and easy.

  • A rugged portable computer with integral display and keyboard is available.

  • Complete system fits in two hand-carried cases.
