Thermocouple Calibration Service

Our company has SANKO CO.,LTD. which has been manufacturing thermocouples, resistance temperature detector, and other thermometers in Japan for many years, as its investment parent. Utilizing the technology cultivated by SANKO CO.,LTD. we also manufacture thermometer in Thailand.

The quality and maintenance of thermometers are very important factors for companies that require heat treatment and strict temperature control.

We not only manufacture thermometers based on many years of experience, but we can guarantee that the thermometer can display the correct temperature by calibrating the temperature.

Please feel free to use our temperature calibration service for your quality maintenance, quality assurance, ISO, etc.

Type of temperature sensors we cancalibrate

・Thermocouple (R-K-J-T)

 Calibration type : Comparison calibration with our standard


 Calibration type : Comparison calibration with our standard

Type of Thermocouple Calibration range Specifiable Temperature
Thermocouple Type R 0℃~1000 Every 100℃
Thermocouple Type K -20℃~1000 -20℃・0℃ after that, every100℃
Thermocouple Type J -20℃~750 -20℃・0℃ after that, every100℃ (Max750℃)
Thermocouple Type T -20℃~350 -20℃・0℃ after that, every100℃ (Max350℃)

Precaution when requesting calibration

・The length part of dimension has a straight shape

・The terminal has a shape that can be connected using alligator clip

・The accessories of the temperature sensor such as terminal box and connector can be removed

※Please contact us in advance, because calibration may not be possible depending on the shape and dimensions of the temperature sensor.
