Features Convenient to Convert: The K type thermocouple module can convert the ambient temperature into a temperature compensation voltage through the internal temperature detection diode. Signal Conditioning Amplifier: The K type thermocouple module internally has a signal conditioning amplifier that converts the thermocouple signal into a voltage compatible with the ADC input channel. High Accuracy: The T and T‑inputs are connected to the low‑noise amplifier A1 to ensure the high accuracy of the detection input and at the same time isolate the thermocouple connecting wire from the interference source. Multifunction: The K type thermocouple probe has 12‑bit analog/digital thermocouple converter, cold junction compensation sensing and correction, digital controller, 1 SPI compatible interface and 1 related logic control. Long Service Life: The K type thermocouple probe has simple structure, anti-interference, small error and long service life. K-type thermocouple temperature probe sensor, with enough quantity and length to meet your daily needs.
