UnverifiedCO（一氧化碳）报警对使用燃气热水器/取暖且宠物长期独处的家庭为刚需，应选带独立CO电化学传感器且报警阈值可调（一级50ppm、二级100ppm）的机型，纯甲醛VOC仪不具备CO防护意义75% similarUnverified甲醛数值必须看传感器类型：电化学传感器精度可达±0.01mg/m³且寿命2-3年，半导体传感器成本低但受温湿度干扰大、数值飘忽，新装修婴儿房应选电化学甲醛模块73% similarUnverifiedCO2检测必须用NDIR（非分散红外）传感器，量程覆盖400-5000ppm；卧室/办公室建议关注CO2，超过1000ppm即需通风。半导体式eCO2是估算值不可信73% similarUnverified家用甲醛检测的关键是传感器类型：只有电化学传感器才能相对特异性地检测甲醛，量程需覆盖0.01-2.00mg/m³且分辨率达0.01mg/m³才能判断是否超过国标0.08mg/m³的限值73% similarUnverified甲醛检测功能在多数过敏原检测仪上采用电化学传感器，寿命仅2-3年且易受TVOC干扰产生虚高，若主要担忧甲醛不应依赖多合一检测仪，专用甲醛仪更可靠73% similar
