7Semi AD8495 Analog K-Type Thermocouple Amplifier Breakout

The 7Semi AD8495 Analog K-Type Thermocouple Amplifier Breakout is a precision analog-output temperature measurement module designed for K-type thermocouples. It uses the AD8495 amplifier, which provides cold-junction compensation and a linear analog voltage output proportional to temperature. This breakout is ideal for high-temperature applications such as furnaces, ovens, industrial processes, engines, exhaust systems, and laboratory experiments requiring wide-range and accurate temperature sensing.
