RTD Probes & Sensors — Pt100 & Pt1000 | In Stock & Custom Made in Australia

RTD Vs Thermocouple — Which Should You Choose?

RTD probes and thermocouples are both widely used temperature sensors, but they serve different applications. Choose an RTD probe when:

• High accuracy and repeatability are required (RTDs are accurate to ±0.1°C or better)
• Operating in the -200°C to +600°C range
• Long-term stability matters (RTDs drift less over time)
• Your application requires compliance with IEC 60751 or DIN EN standards

Choose a thermocouple when:

• You need to measure very high temperatures (above +600°C) • Fast response time is critical
• Cost is the primary concern
