Yunsailing Type K Thermocouple Probe Tl1004 K Type Sensor Probes Metal Mini Connector Temperature Sensor for Meter in Temperature Range from 0 to 500 Celsius(3 Pcs)

These are great! Very robust tips and extremely accurate (tested boiling and freezing point of water).

Inexpensive and seems to take accurate temperature without issue. Using on a coffee roaster. Fresh Roast, drilled a hole through glass chamber with diamond bit.

Put all three probes on a data logger. They seem to eventually reach the same temperature, within +/- one degree F. But the three probes have different response characteristics with respect to noise and time to reach equilibrium with ambient temperature. Smaller (not as thick) as expected. Should've read the dimensions more carefully.

Nice item. Works, Expecially like the metal wrapped cable for the k-type probe.

I have this thing going through my multimeters multifunction adapter and into a cheap multimeter. It reads room temperature until most of the metal shroud is immersed in something or a heat is applied nearly at the cable. I don’t know if this is meant to be an immersion thermocouple or what, but I did buy it for point contact heat reading on my soldering iron— a task it’s not suited well for— which might not be a task it was built for. I have no complaints about the item, I may need better tools to use it.

Very nice temperature sensors. Quality build. Will buy more. Output same between units.

Used a few times under the hood of a vehicle to monitor temperature of coolant to heater core. Accurate temperature with my Fluke meter, nice quality and good value.

These thermocouples achieved accuracy within one degree Fahrenheit when checked in ice water. They seem sturdy with the probe reasonably immune to damage by most chemicals, etc.

Not working. It is open.

One prob broke within two days , and another one not really good
