JJF 1409-2013 《Calibration Specification for the Surface Thermometers》 Related products

JJF 1409-2013 "Specification for calibrating surface temperature meters" is suitable for calibrating surface temperature meters with Thermocouple as temperature sensing elements in the room temperature to 400 ° C Temperature range. This specification refers to JJG 617-1996 "Digital Temperature Indicator" and GB/T 13639 "Analog Input Digital Indicator for Industrial Process Measurement and Control Systems" and other related standards. The surface temperature meter is used for the measurement of solid surface temperature and consists of a temperature sensor and a digital temperature indicator. Its working principle is to press the thermocouple temperature sensing element of the temperature sensor tightly on the surface of the measured object, and display the surface temperature of the measured object through the indicator instrument. The indicator instrument usually has the automatic temperature compensation function of the Thermocouple reference terminal to ensure Measurement accuracy and Stability. Miscellaneous type surface temperature meter calibrate can be carried out with reference to this specification.
