Despite the initial temperature metrology temperature unit, which is also commonly used in daily life. Return is measured Temperatures, which were initially such degrees Celsius (o C) and Fahrenheit (o F), etc. Each unit will have. The difference in temperature during the show itself. Kelvin temperature scale starts from absolute zero, or 0 K by comparing the temperature scale. C is equal to -273.15 o C, but the change in the 1 degree will have the same value. This is different from Fahrenheit temperature scale where the temperature change is equal to 1 o F 1 oC temperature changes or temperature changes 1 K, the relationship between the temperature measured in the three scales can be obtained from the equation in Table 1.
The measure will not have any value or can be available. If the measurement can not be linked. Back to the basic measurement unit of measurement that. Properties are linked in such a results hatco measurement called "traceable" So the traceability of measurements in each country, thus linking the measurement results. All levels to the definition of the base unit of measurement in the International System of Units measure. Through the national standards of each country. Or international standards hatco uninterrupted period.
The basic unit of measurement for temperature is Kelvin (K) capable of temperature traceability. Starting from the transmission of the thermodynamic temperature dynamics in the definition of Kelvin to scale standard temperature ITS-90, which contains hatco the reference temperature in the so-called Fixed Points by devices that are used as primary standards (Primary Standard) in the points. Origin standard temperature (Fixed Points Cells for the thermometer to touch or Fixed Point Blackbodies for non-contact temperature measurement), then the temperature of the sources. The temperature hatco of these standards will be transmitted to the Temperature Measurement standard secondary (Secondary Standard), which consists of Standard Platinum Resistance Thermometer (SPRT) for the thermometer to touch and Standard Radiation Thermometer (SRT) for temperature measurement. Non-Contact The value of four temperature: initial temperature metrology. Will be transmitted to the Platinum Resistance Thermometer (PRT) for the thermometer to touch or Radiation thermometer in the thermometer does not touch and Radiation thermometer is being used as a benchmark to calibrate the scale. Use the thermometer does not touch for example, or Infrared Thermometer Thermal hatco Imaging Camera, etc. But for the thermometer touch in driving.
