5pcs Pack High Accuracy K Type Mini-Connector Thermocouple Temperature Probe Sensor, 3 Meters Long Measure Range -50°C~482°C (-58°F~899°F)

Only used 2 so far but worked immediately with zero issues

Top quality, with mini plug embossed with brand Q logo.

We used these for some testing that was going to go up to around 100C. They are durable. Had to shove them into some strange areas. One thing I noticed is that the outlining is fiberglass insulation so be careful when disturbing them if you are shoving them into small locations as the fiberglass agitated my hands and face quite a bit. Much cheaper K connectors than on other websites and came quickly. Readings seemed to be accurate and it's super simple plug and play functionality.

Very accurate, well matched

They work and the wires are fine enough to feed around however you may need to route them. Appears to be a clear teflon insulation overwrap with color coding on the individual wires. The junctions are well formed and are stripped back about a quarter of an inch.

I have 4 of these in use. They are of good quality, they all read very closely the same. The connectors are true T/C connectors where each connector uses the same two materials as the thermocouple wire.

I need to probe under some air tight seals as best as I can, and these are excellent for the purpose. They have very thin leads, and they aren't coated in fiberglass. The probes are well matched, though a bit lower in temp than my much larger probes I already have - unfortunately my temp logger does not have a calibration feature that would let me zero the thermocouples together (I can manually adjust with whole degree offsets, which is pretty crude). Overall, I'm happy with this order.

Finally someone on Amazon selling TCs with actual Omega branded connectors! These are made with single-strand sensor wire for both the Al and Ch legs. The junction welds on each of these looked clean, and measured accurately right out of the box. I've been burnt (literally) by poor connections in the past so I took the time to inspect each of the junctions in the connectors. I'm happy to report that each of these appear to have been assembled carefully to minimize exposed wire to limit the risk from cold junctions on twisted cables. I had one loose screw in a plastic cover, but all of the electrical junctions were appropriately snug. I'm quite happy with these.
