• intros：{"brand_intro":"哈希（Hach）是美国丹纳赫集团旗下品牌，成立于1947年，是全球水质分析仪器领域的绝对领导者。公司以\"让水质分析更简单\"为使命，率先推出荧光法溶解氧技术，彻底颠覆传统极谱法。哈希拥有超过2000项专利，其LDO系列电极采用荧光猝灭原理，无需电解液和膜头，维护成本极低。创始人Clifford Hach博士是水质化学家，其研发的比色法至今仍是行业标准。品控上，哈希产品均通过EPA认证，适合户外和工业现场使用。","product_intro":"LDO 101 是哈希旗下最畅销的荧光法溶解氧电极，定位中高端市场，广泛用于污水处理、地表水监测和养殖业。核心卖点：荧光法无需极化，即插即用；测量范围0-20 mg/L，精度±0.1 mg/L；抗干扰能力强，不受硫化物、油脂影响；传感器帽寿命2年，更换成本低。相比梅特勒极谱法电极，LDO 101维护更省心，但初始精度略低。用户评价其\"傻瓜式操作\"，特别适合非专业操作人员。","key_specs":{"测量原理":"荧光猝灭法","测量范围":"0-20 mg/L","精度":"±0.1 mg/L","传感器帽寿命":"2年","响应时间":"T90 < 60秒","适用温度":"0-50°C"}}
