Thermostat 150 degrees. After stabilization of the oven temperature, good surprise, the displayed temperature is 150 degrees hair cell. It sounds silly, because the thermometer is made for this, but I hate the "almost", and medium-quality purchases.
Second pleasant surprise: I had read reviews on other brands that thermometers yellowed from the first use, for lack of a good seal. But with that I bought, no problem. After several weeks of daily use, it retains its original appearance and readability.
