Review on Oumefar Thermometer0℃ 700℃ Thermometer Reliability Thermocouple by Joe Glass

Instructions in Chinese. Google Translate does this pretty well, but it's very easy to use: grab one of the triangular wire thermocouples. They have a red sleeve on one leg, a blue one on the other, and one sleeveless - pin the red and blue sleeves onto the pins next to the reading and blue circles. Press the button at the top and slide the sleeveless wire over it and release the button to tighten everything. Place a black rubber washer under the center of the triangle to protect the panel below. I found a way to get accurate measurements that I don't think the manual makes clear to make sure there is some solder on the metal. Tongue in the middle, soldering tip regularly with rosin flux (especially when testing at high temperatures, which quickly oxidize the tip), and touch up the solder on the tongue from time to time. Readings even when a liquid flow acts as a heat conductor.
