Temperature Sensor Thermocouples are electrical devices developed using two different metals linked at one point. They are developed to function over a huge range of temperatures from -200Â°C up to 1250 Â°C. They are widely used in steel and iron industries as they can easily provide the best performance in extreme temperatures. These Temperature Sensor Thermocouples are ideal to provide accurate results as they are designed using high-technologies and conductive materials. They are provided in varied specifications in durable and sturdy body to provide precise results.
