3 pcs K Type Mini-Connector Thermocouple Temperature Probe Sensor K Type Thermocouple Wire Temperature Sensing Line Measure Range -40 to 400 Celsius, Compatible with TM902C/ TES1310 (2 Meter)

Works ok. Freezing water temp came up as 40 degrees F, instead of ~32F, even after 10 mins to get to equilibrium. Worked with both MAX6675 and MAX31856 amplifiers. Tested in an oven up to 500F, but I could not determine the accuracy because I did not have a good reference. Reaction time is quick, implying a low thermal mass.

Needed these to complete a temperature controller for my smoker BBQ. They are exactly as described and will fulfil the requirements.

Was just right!

I remember when I discovered thermocouples - they were a game changer. With one reader, I can measure the temperature of virtually anything, at virtually any temperature, with extraordinary accuracy. I keep a couple of inexpensive PVC-jacketed probes with it for normal "thermometer stuff", and a some fiberglass jacketed ones, some over 15' long, for more exciting stuff. I even have a couple of the "probe style" permanently mounted in my smoker - when I'm cookin', I just plug in the reader and I'm off to the proverbial races. In any event, these are, in fact, thermocouples. They appear to be accurate, for less than $10 for 3, they're inexpensive enough, and they'll measure from -40℃ to 400℃, far outside the range of any household thermometer.

This is a good set of three K-type thermocouple for temperature measurement. The probe worked fine and temperature reading was close to another probe from major name brand. However, One out of three probe did not have the thermocouple end fused. I have added the picture. I don't need all three now, but if I needed I was out of luck. I took a star for that.
