The K Type Thermocouple 400 °C Temperature Sensor is a simple and reliable device used to measure temperature up to about 400 °C. It has two different metal wires joined at one end that produce a small voltage when heated, which controllers or meters can read as temperature. This sensor is tough and works well in many environments, including ovens, furnaces, and machines. It responds quickly to temperature changes and delivers consistent readings. The sensor is easy to install and widely used wherever accurate temperature monitoring is needed. Features Accurate temperature sensing up to 400 °C Fast response to temperature changes Durable and heat-resistant construction Works with many temperature controllers and meters Simple solid-state design with no moving parts Specifications Type: K-type thermocouple temperature sensor Temperature range: Up to 400 °C (approx.) Output: Millivolt signal proportional to temperature Material: Chromel-Alumel junction Connection: Standard thermocouple wire lead Uses Temperature measurement in ovens and furnaces Industrial process temperature monitoring Use with digital temperature controllers and meters Heating system and HVAC temperature checks Laboratory and workshop temperature sensing Packages Include: 1 x K Type Thermocouple 400C Temperature Sensor
