Review on 🌡️ MYPIN TA4-SNR+K Dual Thermocouple Temperature Controller with PID and Digital Display, Dual Type-K Thermocouple by Johnnie Bowlan

I installed two type K thermocouples next to each other. You control the PID. The other goes to a new digital handheld thermometer with a new calibration certificate. There is nothing I can do to make the PID match the thermocouple value. The PID function is worse than turning it off. The temperature behavior of a PID controller is not stable, so the offset setting often needs to be adjusted and then readjusted, but it never stays the same with a thermocouple meter and the difference increases over time. In short, this block doesn't offer meaningful temperature control, at least for my purposes.
