This K type thermocouple wire for common thermocouple wire, thermocouple standard line, can be suitable for K type imported and domestic temperature recording instrumentation.
 
Precision and ordinary of the difference: ordinary line density than the precision line is low, the gap is larger, seems to be about the same, due to the principle of thermocouple is due to the two different materials of the metal generated by the thermal electromotive force, only a few millivolts, so there is a little bit of interference will reduce the measurement accuracy, of course, the requirements of the user can not be high choice! 
 
Ordinary Wire: Thermocouple wire in high temperature environment will produce shunt effect, is due to the temperature rise of insulation material insulation resistance to reduce the result, and the temperature of the insulation material to reduce the resistance.
 
Precision Wire: insulated by double-layer high-temperature fire-resistant fiberglass (ordinary single-layer), effectively reducing the shunt effect, to protect the accuracy of long-distance measurement!
