温控精度越高、功率越大越好，但两者叠加会推高价格，日常做鸡胸/牛排选±0.5℃+1000W足够，追求分子料理级精度才需±0.1℃

Unverified精度选±0.5℃或±1℃的产品用于肉类烹饪足够（低温慢煮除外），标注±2℃以上的廉价款判断五分/七分熟会出错81% similarUnverified精度误差±0.5℃以内适合低温慢煮和精准烘焙；±1℃对日常肉类熟度已足够；表盘式机械温度计误差常达±2℃且无法校准，不适合对温度敏感的料理80% similarUnverified温控精度需≤±0.5℃，牛排等对熟度敏感的食材建议选±0.1~0.2℃机型，误差1℃就可能从三分熟变五分熟79% similarUnverified控温精度越高（±0.5℃）的PID温控芯片成本越高且加热速度越慢，日常冲奶±1℃已足够精准；追求秒速烧开会牺牲控温稳定性，两者难兼得78% similarUnverified温控精度需≤±0.5℃才能保证低温慢煮效果，牛排理想熟成范围仅相差2-3℃（54℃三分熟vs57℃五分熟），精度±1℃以上会导致成品口感不稳定78% similar
