High-Temperature resistance for demanding conditions.

SMARTRAC’s HT-GLASS-TAGS have been specifically designed to meet the demanding requirements of the chemical industry as well as the oil, gas and drilling industries. Made from specific components, the HT SMART-GLASS-TAGS offer high resistance to harsh surrounding conditions, in particular resistance to high-temperature, mechanical stress and most chemicals. The high-temperature glass tags have been successfully tested in applications with temperatures of more than +125°C.


Operating in the LF frequency, the tags provide reliable read range and excellent performance in the presence of metal. The small yet robust glass tags can be easily attached to or inserted into objects. This makes them an ideal fit for tracking and tracing of tools and parts.


SMARTRAC’s HT-GLASS-TAGS contribute to reduce replacement costs for valuable tools and parts. They passive RFID tags also contribute to working safety and production control.
