Thermocouples are one of the commonly used temperature detection sensors in industry, civilian use, testing, and scientific research, with high measurement accuracy. Thermocouples are in direct contact with the measured medium and are not affected by intermediate links, which cannot be replaced by infrared thermometers. Thermocouples can measure continuously from -80~+2300 ℃, and some special thermocouples may have a wider range. Our company independently produces customized thermocouples to meet various needs.
