I don't remember whether your oven is gas or electric. Mine (at home) is electric. I was unpleasantly surprised to learn that it significantly overshoots the target temperature when preheating, then cycles wildly when it is supposed to be at the set temperature. That alone was a valuable lesson from this particular lab, but it took a while to figure out why the sugar was melting at such unexpected temperatures!
It is electric. And so far lives up to my expectations. I have always said it was very accurate and the sugar melted between 360 and 370 Fahrenheit. Next time I am bored I will set it for exactly 366 and see what happens. It's digital so I can do that. Right now I'm doing the second part of that lab which involves putting a oven thermometer in there and seeing if it reads accurately. But I have more trust in my oven than in the thermometer! So it will be interesting to see. This thermometer is slow to respond.
