24HP-01-1 Oven Thermometer, NSF HACCP SS 100 Degree F/600 Degree C

Accuracy and clarity of the dial

Temperature readings match those in my oven which is what I wanted to test.

Muy buen termometro, relacion calidad precio perfecta cooper atkins es sinonimo de precision, antes teniamos un kitchenaid que lo unico bueno que tenia era el nombre, si estas buscando y llegaste hasta aquí no lo pienses mas.

It's tiny and compact. Barely occupies space and works like a charm.

Fairly quick respond to temperature changes. As far as I can tell, temperature is accurate enough for pizzas, turkeys, potatoes, and squash. The base is wide enough for stability on the rack and the hook is useful for hanging under the rack. Overall, a great tool.

I bought two of these because the spec said its accuracy is ±25°F and I wanted to get readings from two side-by-side gauges to observe potential variance in testing the pre-heating of my new oven (a Whirlpool GGG390LXS). Sure enough, one of these thermometers read about 20°F greater than the other. An important finding of this test was that although the final temperature of my oven for this test (350°F) was reached fairly accurately, it seemed at first that my oven pre-heat was very slow, that is, it took about five minutes longer to reach the 350°F than when the oven controls said full temperature was reached.Then it occurred to me that perhaps the oven was correct and the gauges are simply slow to respond to temperature changes. So I repeated the test using a thermocouple on an electronic multi-meter. It turns out that the oven was very accurate and in fact cycles above and below the set temperature by about 15°F. I.e., the 350°F temp is "held" actually by heating up to 365°F, then the gas goes off, it cools to 335°F, then the gas burner goes back on, and repeats this up and down. Thus, since the Cooper Oven thermometer has a much slower response time than an electronic thermocouple, you get the average temperature. And you would normally want this to be the case.I wrote up the above test results in case someone else, like me, was testing the time it takes to pre-heat the oven. Because of the slow response time of this type of gauge, don't use it for that purpose. However, it does a good job as intended in monitoring the relatively steady state temperature in the oven. For an instant measurement, you need to use a thermocouple.As a final note, on the initial preheat, the temperature (as read by the thermocouple) actually shot up to 390°F and then proceeded to the cycling of 350°F ±15°F as described above. I believe this is by design because when this oven's control panel says preheat is completed and put in the food, it knows you will be opening the oven momentarily to put in the food and the temperature will drop while the oven is open. This initial overshoot helps compensate for that loss.

Works great ! Now I know what the temperature is when I get that turkey soon.
