Dry high-temperature measuring points often leave little room for bulky probes. The GTF 300 GS family uses fine 0.2 mm Type K thermocouple wires to measure quickly in air, gases and on very small surfaces, with an approx. 0.3 s response time for fast temperature changes.
The glass filament insulated version extends the measuring range up to +400 °C and is optimized for dry environments. Class 1 accuracy gives users a dependable basis for portable checks, test setups and temperature measurements where a flexible wire probe is easier to place than a rigid sensor.
The family covers several practical configurations. Users can select twisted and welded tips, untwisted welded tips or a weld bead, with cable lengths of 1, 2, 5 or 10 m. Connection is available via a miniature flat-pin plug with kink protection or loose ends with wire end ferrules.
The probe uses NiCr-NiAl Type K thermocouple wires with a fine wire diameter of 0.2 mm.
The cable is glass filament insulated and intended for dry environments.
The family includes twisted and welded, untwisted welded and weld bead measuring tip versions.
Versions are available with miniature flat-pin plug with kink protection or loose ends with wire end ferrules.
Standard selectable probe cable lengths are 1 m, 2 m, 5 m and 10 m; other lengths are available on request.
With a suitable display device, the probe can be supplied with DAkkS/ACCREDIA-accredited ISO/IEC 17025 or ISO 9001 calibration.
