Technical data:

Measurement range, resolution:

• GTH 2448/1: -50 to +1,150 °C (NiCr-Ni)
• GTH 2448/2: -200 to + 650 °C (Pt100, 2-conductor)
• GTH 2448/3: -60.0 to +199.9 °C (Pt100, 2-conductor)
• 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)

• The sensor”s zero offset (e.g., caused by a long cable) can be adjusted with the aid of the offset trimmer on the rear of the device.
