Poor and sensitivity without the permission of the K type thermocouple is what mean?

Poor without the permission of the K type thermocouple is 1 ℃, if want to use it a thing on both sides of the temperature measurement, look have 1. 3 ℃ temperature difference ( 36 ℃ or so) , this allows the difference how to understand, is zero drift? Or is very irregular with the error of plus or minus 1 ℃, on both sides that I measured a 0. The difference in temperature of 5 ℃, it might not be able to tell me which high temperature on both sides? If the latter, it is not as good as mercury thermometer and so on. In addition, the sensitivity and how to understand? Under xiamen branch's son said to give you a k type thermocouple allow poor sensitivity and the general meaning, basically has the following five points:

1, the tolerance of k type thermocouple is 1 ℃, use it to measure a thing on both sides of the temperature, look have 1. 3 ℃ temperature difference ( 36 ℃ or so) , any kind of thermocouple, can do, although it is cold, but the thermocouple measuring temperature range has been covered.

2, how do you understand this tolerance, according to the standard requirements, within the permitted error, the existing common standard: GB, JB, you require tolerance can be achieved, if is normal manufacturer production thermocouple, will according to your request for your tolerance, the tolerance control within your request, like Beijing instrument huashi company with many years of production experience, can be done.

3, according to your question, I think you may be doing a test, this must look for professional manufacturers.

4, sensitivity: is the response speed of the topic, this problem has two aspects, one is, thermocouple, and the display table, the thickness of thermocouple and sensitive with a kind of contact, but the thermocouple during production process and sensitive with the related factors of the secret inseparable, about the display table, table rate is also very important, the hidden, to achieve a goal.

there are: like compensation wire, distance, measured the correct installation, these will form some potential associated with precision.
