The temperature of a material in a weathering test is one of the primary factors that cause material degradation. Measuring specimen temperature during accelerated tests is difficult and usually requires interruption of the test cycle. To address this limitation, a new S3T (specimen-specific surface temperature) technology can provide accurate surface temperature measurements for materials under a range of weathering test conditions.

The system uses a non-contact thermal infrared sensor (pyrometer) facing the exposed specimen surface to provide accurate temperature profiling during test exposure. An RFID system is used for automatic sample indexing and identification. The temperature data can be viewed in a table or trend plot format on a new full-color touch screen display.
