This is followed by type e (±1.7c or 0.5%) and types j, k and n (±2.2c or 0.75%) for standard limits of error (per ansi/astm e230). Wide range is −270 °c to +740 °c and narrow range is −110 °c to +140 °c. What is the difference between t type and k type thermocouples?

They consist of iron wire in.
Not suitable for temperature above760°c. The curie point of iron is 770°c, at which point the magnetic field of the iron wire begins to change its behavior, causing any voltage readings to be unreliable. The different thermocouple types have different temperature ranges. Autoclave k type thermocouple :
As mentioned above, it can read temperatures from 0 to 750°c, and this is due to its composition of iron and constantan.
The temperature range of these types of thermocouples is from 32 till 1400 degrees fahrenheit. Type j accuracy (whichever is greater): Type k on the other hand can be used up to 1260c. Low temperature and cryogenic applications.
It has a smaller temperature range and a shorter lifespan at higher temperatures than the type k.
(0 to 760) °c [32 to 1400] °f. Choose from our selection of type j thermocouples, including over 200 products in a wide range of styles and sizes.

It is not susceptible to aging in the 371 to 538°c,.
The color for these thermocouples is either red or white. Choose from our selection of type j thermocouple wire in a wide range of styles and sizes. The type j thermocouple is suitable for vacuum, reducing, or inert atmospheres, oxidizing atmosphere with reduced life. It is equivalent to the type k in terms of expense and reliability.

Type t thermocouples have the tightest accuracy of all the base metal thermocouples at ±1c or ±0.75% whichever is greater. A j type thermocouple range falls between these two extremes. Alumel is having 5 percent nickel and rest is silicon and aluminum. In stock and ready to ship.
Table 7 type j thermocouple thermoelectric voltage as a function of temperature (°c);
It is equivalent to the type k in terms of expense and reliability. The type k thermocouple is having chromel as their positive leg and an alumel as their negative leg. The type j is also very common. The type j is also very common.
