K-type Thermocouple Temperature Sensor Probe

The K-type Thermocouple Temperature Sensor Probe is a reliable and precise temperature measuring solution suitable for high-temperature environments. Made with Chromel and Alumel alloy conductors, this thermocouple offers excellent resistance to oxidation, corrosion, and thermal stress. With a tolerance of ±1.5 and an operating temperature range up to 2000°C, it’s ideal for industrial, laboratory, and electronic applications.

Unlike J-type thermocouples that use iron and constantan, the K-type uses nickel-based alloys for greater durability and performance in acidic or oxidizing environments. The probe includes a 110cm long wire for easy installation, a built-in cold junction compensation circuit, and supports a simple 3-wire SPI interface. This sensor is designed to convert temperature readings into 12-bit digital signals and features built-in thermocouple break detection for safety and diagnostics.
