WJT-223 thermocouple automatic calibration device use new computer technology which is easy to operate, high automation, reliable testing technology and stable performance. It is exclusively for industrial thermocouple such as platinum 10 - Platinum (S), Ni-Cr and Ni - Si (K), nickel-chromium - Examination of copper (E) thermocouple. Its approach is comparative method that is directly compare second-class standard platinum rhodium 10 - platinum thermocouple with the thermocouple to verification and indexing.

 

WJT-223 is completed device which includes microcomputer control system and heating and voltage regulators. Computer control system including: digital voltmeter, computer, printer, and control box; Furnaces and voltage regulator including: tubular test furnace, SCR voltage regulator, second standard S thermocouple and control-temperature S thermocouple.

 

This device is suitable for industrial and mining enterprises, scientific research and measurement sector.
