Review on Advanced Hotloop Digital Oven Thermometer - Ultra Heat Resistant up to 572°F/300°C by Heather Lawson

I needed an oven temperature gauge that I could see without opening the oven door. This got the job done after a small tweak. Explanation: There really is no oven temperature. The oven itself has a thermostat. When the thermostat thinks the oven is too cold, it turns on full heat. When the thermostat thinks the oven is hot enough, it turns off the heat. If the oven is set at 350 F, the air temperature near the heating element will likely be between 300 F and 500 F. The air temperature near the thermostat will likely be between 325 and 375. What really matters is the temperature of the cake in the center of the oven. The problem with this hotloop digital oven thermometer is that it is too sensitive. Its sensor measures the temperature of the air near the sensor and varies widely. In order for the probe to measure what the baker thinks is "oven temperature," he needs to measure the temperature of something so massive that it stays at around 350 while the air around it changes as above. In my college science classes, this was called "thermal mass" and the effect was called "thermal inertia." I bought some "JB Weld 8297 HighHeat 550 Grade Epoxy Putty Sticks". It is marketed for tasks such as muffler repairs. Regular epoxy doesn't like high temperatures, but unsmeared epoxy has the texture of cold maple syrup. I used epoxy putty to make a plug the size and shape of my thumb and buried the probe inside the plug. After the epoxy had cured, I placed the probe in the oven and attached the hotloop digital oven thermometer to the nearest surface using "BRAVESHINE Adhesive Reversible Coins with Adhesive Double Sided Removable Adhesive Pads". It works like a charm. A piece of epoxy putty will hold enough heat for the thermometer to read an average temperature rather than the up and down swings caused by how thermostats work. and saw the probe's temperature rise to about 95°F in a minute or two and then gradually cool back down during the "1 hour cure" interval. I didn't know that epoxy curing is exothermic.
