BQLZR Temperature 100 1250 Thermocouple Sensors Review

The probe didn't measure accurately, was wildly over the scale, when I told the supplier they didn't even bother to contact me for a replacement.

This sensor was extremely inaccurate. I used it in a pressure cooker connected via a PID controller. Temperature readings were everywhere. I have used other sensors for the same setup. The rest of the sensors worked great. Other probes were sold out and I needed a longer one, so I tried this one. This sensor kept changing within a 4 degree difference and could not allow the PID controller to keep the temperature exactly in the desired range.

This thermocouple was used with an old Fluke thermometer to measure the temperature of molten bronze during casting. Installed it on a steel tube as a handle; tested it by dipping it in a crucible when the copper charge was about half melted; The observed temperature was 1981 degrees Fahrenheit, about two degrees below the textbook melting point of copper. Very good results for the price. The only problem was that after a few seconds the spring on the cable started to melt and the bare part of…
