Reliable Module

Bought five for our lab. All working perfectly without any calibration issues.

5 FAQ

Q: What is the maximum wire length for the probe?

A: We recommend keeping extension wires under 2 meters for best accuracy.

Q: Can I use J-Type thermocouples with this?

A: No, this chip is calibrated specifically for K-Type thermocouples.

Q: Does this module include the thermocouple probe?

A: No, this is only the interface module. Probes are sold separately.

Q: What library do you recommend for Arduino?

A: The standard Max6675 library available in the manager works well.

Q: Is this compatible with 3.3V logic?

A: Yes, it operates between 3.0V and 5.5V so it works with 3.3V boards.
