農業及畜牧業的應用：農業及畜牧業生產，尤其一些經濟作物的生產，在其幼苗期要詳細記錄溫濕度記錄儀值。而在農業應用中，由於惡劣環境――肥料、糞便等造成的酸堿性環境使濕度產品漂移超出其他環境，這樣就要求濕敏電容漂移較小、整機校準方便。
      建築驗收：主要體現在智能樓宇的驗收。由於建築行業的驗收項目多，除暖通空調指標外，其他諸如射線強度、jiaquannongdudengjianzhubuyaoqiufuherentijiankangzhibiaoyeyaojiance，zhexiezhibiaoshizhijieguanxidaorentijiankangde。ruguozaizhexiezhibiaobumingledeqingkuangxia，ceshirenyuanmaoranjinruzhexiechangsuobingchangqizaiqijianjinxingjilu，shiduiceshirenyuanderenshenjiankangdebufuzeren，eryingyongjiluyijiuhuibaozhengzaiqudekekaoshujudetongshiduiceshirenyuanderenshenanquanjinxingzuidabaohu。
      重要醫衛場所：按照《醫院潔淨手術部建築技術規範征求意見稿》的要求手術室的溫濕度記錄儀必須控製在一定的範圍內：即溫度在22…25℃；相對濕度45％RH…60％RH。適宜的環境溫濕度記錄儀對操作者和病人都是非常重要的。當室溫超過28℃，濕度大於70%RH時，易有悶熱、出汗、煩燥、疲勞等反應，容易影響安定的情緒和敏捷的思維，使操作者的技術水平不能得到很好的發揮。同時病人也會出現心率快、出汗多等症狀而增加手術難度；當室溫低於20dushi，zhichuanshoushuyidecaozuozhehuigandaoleng，yiyingxiangcaozuodongzuodelingminxinghezhunquexing，youqishishouzhidexiweidongzuo。luoludebingrenyouyuchuangshangjitidikanglichuyudixiashuiping，gengyifashengganmaodengbingfazheng。shineishidudi，wutibiaomianfuchensuimouxiedongzuo，rupudan、開關門等造成氣流改變而懸浮在空氣中。手術間內外溫差大，開門後部分區域的空氣形成蝸流，風速增大到約手術間原風速的4倍，此時物體表麵附著物迅速飄浮於空氣中。根據美國CDC的調查表明手術室空氣中浮遊菌數在700-800cfu/m3時就有經空氣感染的危險。從結果可見，手術時鋪單至鋪單後2xiaoshikongqiwuranzuiyanzhong，cishizhengshishoushujieduan。youyushouzhonglizuoyong，shineipiaochenkezhijiechenjiangdaoshoushuchuangmian，huocaozuozhedeshouhuoshoushuqixieshang，yincijiaqiangkongzhiciqidekongqiwuranduiyufangshuhouqiekouganranshizhiguanzhongyaode。zhexieyaoqiuweishengfangyibumentongguozijidejiancequerengeyiyuanshoushushidedabiaoqingkuang，jiluyishiyizhonghenhaodefangfa，jianshaolerenyuanlangfei，bingshizhifadegongzhengxingdedaobaozheng。
