- GTH 2448/5: -60.0 to +199.9 °C (Pt1000, 2-conductor)
Precision: (at nominal temperature = 25 °C)
- NiCr-Ni: ±1% ±1 digit (from -20 to +550 °C or 920 to 1,150 °C)
- NiCr-Ni: ±1.5% ±1 digit (from 550 to 920 °C)
- Pt100, Pt1000: ±0.5 °C ±1 digit or ±1 °C ±1 digit
Offset adjustment: (only with Pt100 and Pt1000)
