• intros：{"brand_intro":"上量成立于1958年，前身是上海量具刃具厂，是中国最早生产扭簧比较仪的企业之一。品牌以\"上海制造，精益求精\"为口号，在长三角地区拥有极高知名度。上量注重实用性与成本控制，产品线覆盖从0.01mm到0.001mm全系列。其品控采用\"三级检验\"制度（自检、互检、专检），虽然精度不如进口，但一致性稳定，是职业院校和个体作坊的标配。","product_intro":"SL-205是上量最畅销的经济型扭簧比较仪，定位入门级教学与粗加工检测。核心卖点是0.005mm分辨率配合680元低价，适合对精度要求不高的场景。表盘采用塑料外壳减重，整体仅200g，便于携带。测杆带橡胶防尘套，延长寿命。适用于木工机械、建筑钢材、塑料管材的粗略跳动检测。相比成量，其精度低一档，但价格再降60%，是\"能用就行\"的极致选择。","key_specs":{"分辨率":"0.005mm（5μm），满足IT10-IT11级公差","量程":"±0.02mm，适合粗加工余量检查","重复精度":"3μm，符合JB/T 10031-2019标准","表盘材质":"ABS塑料+亚克力面板，轻便但易刮花","测力":"1.2N固定，无调节功能","重量":"200g，可单手操作"}}
