These high-quality Type K thermocouples (NiCr-NiAl) are specifically designed for applications that require extremely fast response times and maximum flexibility. With a fine thermocouple wire diameter of just 0.2 mm and a fast response time of approximately 0.3 seconds, they enable lightning-fast measurements in air, gases, on very small surfaces, and in liquids (GTF 300 only).
Two insulation variants are available for optimal adaptation to the application site: The Teflon-insulated version (GTF 300) is waterproof and chemically resistant, making it ideal for demanding measurements up to +300 °C. The glass filament insulated version (GTF 300 GS) is optimized for dry environments and covers an extended temperature range up to +400 °C.
All probes comply with accuracy class 1 – the highest accuracy class for thermocouples – and are available with three different tip configurations (twisted/welded, untwisted welded, or with a weld bead). Connection is available via a miniature flat plug (optionally with kink protection) or loose ends with wire end ferrules, available in cable lengths of 1, 2, 5, or 10 meters (other lengths available upon request).
