• intros：{"brand_intro":"上海一恒科学仪器有限公司成立于1997年，是中国实验室基础设备的老牌厂商，以培养箱、干燥箱、加热板等产品闻名。品牌定位\"实用、经济、可靠\"，产品广泛用于中小学实验室和职业院校。一恒拥有自主温控芯片研发能力，品控通过ISO 9001认证，售后网络覆盖全国地级市，是入门级市场的绝对主力。","product_intro":"YK-200是一恒的入门级加热板，采用不锈钢面板，最高温度400°C，功率800W。核心卖点是\"极致性价比\"——价格仅千元出头，却具备数字控温和过温保护功能。适合基础化学实验、样品烘干和教学演示。相比大龙和奥豪斯，一恒在面板材质（不锈钢而非陶瓷）和控温精度（±3°C）上有所妥协，但价格仅为1/3-1/4，是预算极度有限时的首选。","key_specs":{"加热面板材料":"304不锈钢，耐腐蚀但易留划痕","加热功率":"800W，最高温度400°C","控温精度":"±3°C，数字显示","安全功能":"过温保护、熔断器","适配场景":"中小学实验、样品干燥、基础加热"}}
