What temperatures can be measured with K- and T-type thermocouples?

The corresponding temperature range of thermocouples is defined by JIS standard. 
The measuring range of this instrument is in accordance with the JIS standard. 
When K-type thermocouple is selected, -200℃ to +1370 ℃. When T-type thermocouple is selected, -200 ℃ to +400 ℃. 
When T-type thermocouple is selected, -200 ℃ to +400 ℃. 

The heat resistance of the coating causes differences in the temperature range of thermocouples sold, even if they are of the same standard. When purchasing thermocouples, please check the measuring temperature range. 

In the case of thermocouples that we sell as an optional item
