Ordered these to replace a thermocouple that reads 15°C. I tested them at 200°C and they all matched (within 1-2°C) a thermocouple I trust. This isn't the highest quality thermocouple you can buy, but at around $3 each, I'm happy with the purchase. I wouldn't want to run them at 400C max for long periods of time, but at the temperatures I use them for (less than 250C) they seem to work great.
