Unverified85% confidenceDecision RuleTime unknown
湿度计标称精度多在20~80%RH中间量程达标，两端（<20%或>80%RH）误差显著放大；北方冬季干燥（<20%RH）或南方回南天（>90%RH）监测时应看全量程精度而非典型值

Unverified温度精度±0.5℃、湿度精度±3%RH是消费级温湿度计的可信门槛；标称湿度±2%RH的产品需查看是否为整量程精度，多数廉价产品仅在40-60%RH区间达标82% similarUnverified标称日除湿量的测试条件是关键：国标GB/T 19411多按30℃/80%RH，实际家庭环境常在25℃/60%RH，真实除湿量约为标称值的50-60%，选购时按标称值打对折估算79% similarUnverified湿度控制精度看回差范围：优质机型湿度回差≤±5%RH，能稳定维持设定值；廉价机型回差达±10%RH会导致频繁启停或湿度波动大79% similarUnverified温湿度监测精度通常±1-2℃、±5%RH，仅作参考不能替代专业温湿度计；不要仅因带温湿度功能而为其支付大幅溢价79% similarUnverified除湿机标称日除湿量为30℃/80%RH工况下的实测值，实际使用环境（如20℃/60%RH）除湿量通常只有标称值的40%-60%，选购时按标称值打5折估算真实能力79% similar
