Specifications

What Is a K-Type Thermocouple?

K-type thermocouples are the most widely used thermocouple type in industrial, laboratory, and DIY applications. They are made from two dissimilar metals (Chromel and Alumel) that generate a small voltage proportional to the temperature difference at the tip. This makes them highly reliable for a broad spectrum of applications, from ovens and kilns to HVAC systems and industrial machinery. Learn more about thermocouple standards and electrical measurement at the NIST Temperature Measurement Resource.

Common Applications

• PID temperature controllers (REX-C100, SSR-based systems)
• DIY kilns, reflow ovens, and soldering stations
• HVAC and industrial heating systems
• 3D printer heated bed or hot end monitoring
• Brewing, fermentation, and food processing equipment
• Laboratory and research temperature monitoring

Important Notes

• Photos may not reflect actual size — please refer to listed dimensions.
• Allow 5–10mm variance due to manual measurement.
• On-screen colors may vary slightly due to monitor settings.
• Battery not included (not required).

Frequently Asked Questions

Q: Is this K-type thermocouple probe compatible with the REX-C100 temperature controller?

A: Yes, this probe is specifically designed for use with the REX-C100 PID temperature controller and is compatible with any standard K-type thermocouple input device. Simply connect the two leads to the K-type input terminals on your controller.

Q: What is the difference between the 1M and 2M cable versions?

A: The 1M cable (39.37 inches) is ideal for compact setups where the controller is close to the sensing point, while the 2M cable (78.74 inches) provides extra reach for larger equipment or when the controller is mounted further away. The sensor performance and temperature range are identical for both lengths.

Q: What materials is the probe made from, and is it suitable for high-temperature environments?

A: The probe body is constructed from stainless steel, making it corrosion-resistant and durable in high-temperature environments up to 800°C (1472°F). The M6 threaded mount ensures a secure, stable fit in most standard sensor ports.

Q: How do I install this thermocouple probe?

A: The M6 screw fitting allows you to thread the probe directly into a compatible M6-tapped port on your equipment. Once secured, connect the two color-coded thermocouple leads to the K-type input on your temperature controller or thermostat, observing correct polarity (yellow = positive, red = negative for K-type).
