🌡️ Twidec 1/4" Screw Probe Temperature Sensor K Type Thermocouple with 2 Meters Cable - Temperature Range from 0 to 600°C (Model: LT-104) Review

I was surprised by the quality. 4 worked and accurate. I used these on my exhaust with a haze meter with an extension cord. The wire insulation is fiberglass (superglue if you need to splice) which was recommended by the gauge manufacturer, apparently cheaper Teflon and must not be used. I recommend this purchase without hesitation. I will definitely buy again.

The problem is there is less than 1/32" between the bottom of the threads and the inside diameter of the thread gauge ring, probably just under 1/64" that is the only thing holding the threads together so very little tightening force is required to loosen the steps. The threaded part has a 1/4-20 loose fit. The probe is 0.15 inch in diameter and hangs in a threaded ring. The spec for the smaller thread diameter for 1/4-20 is .210", although this gauge is even smaller as it fits loosely.

I was surprised at the quality. I ordered 4 and all 4 worked and worked correctly. Extension wire.

The problem is that between the bottom of the thread and the inside diameter of the threaded brass ring is probably less than 1/32 inch about 1/ 64 inches which is the only thing holding the threads together so very little torque is required to loosen the stages.

I was surprised by their quality. I ordered 4 and all 4 worked and worked exactly. Fiberglass (superglue if you need to glue) recommended by the gauge manufacturer is obviously cheaper Teflon and can't be used. I recommend this purchase without hesitation. I will definitely buy again.
