• intros：{"brand_intro":"哈希（Hach）成立于1947年，是美国丹纳赫集团旗下专业水质分析品牌，全球市场占有率超30%。创始人Clifford Hach博士发明了第一台便携式比色计，奠定了水质快速检测基础。哈希以\"让水质分析更简单\"为使命，在荧光法溶解氧技术领域拥有20余项专利。其LDO系列电极采用荧光猝灭原理，无需电解液和膜帽，维护成本极低，被环保部列为推荐产品。品控通过ISO 14001认证，中国区设有上海研发中心。","product_intro":"LDO II 是哈希第三代荧光法溶氧电极，专为污水厂、地表水监测及工业废水处理设计。核心卖点：无需极化、无需电解液、无膜帽更换，传感器寿命长达2年。测量范围0-20 mg/L，精度±0.1 mg/L，响应时间T90<60秒。与梅特勒极谱法电极相比，优势在于免维护和抗污染能力强（适合高悬浮物水体）。适配哈希HQ系列仪表，支持蓝牙无线传输。","key_specs":{"测量原理":"荧光猝灭法，无耗材，免维护","测量范围":"0-20 mg/L，精度±0.1 mg/L","传感器寿命":"2年（标准使用），到期自动提示","抗干扰":"不受硫化物、油类污染影响","适用环境":"0-50℃，0-3000m海拔，IP67防护","适配仪表":"哈希HQ30d/HQ40d，即插即用"}}
