溫濕度計校準方法
將(jiang)標(biao)準器(qi)(qi)的(de)(de)(de)(de)探頭(tou)置(zhi)于溫(wen)濕(shi)度檢(jian)(jian)(jian)定(ding)(ding)(ding)箱工作室的(de)(de)(de)(de)中(zhong)心位(wei)置(zhi),被(bei)檢(jian)(jian)(jian)儀器(qi)(qi)置(zhi)于檢(jian)(jian)(jian)定(ding)(ding)(ding)箱工作室的(de)(de)(de)(de)有效空間內(nei),放置(zhi)的(de)(de)(de)(de)方式與數(shu)(shu)(shu)量應(ying)不影響(xiang)箱內(nei)空氣循環(huan)。按照從低濕(shi)到(dao)高濕(shi)的(de)(de)(de)(de)順(shun)序進行檢(jian)(jian)(jian)定(ding)(ding)(ding),檢(jian)(jian)(jian)定(ding)(ding)(ding)點依次為:40%RH,60%RH,80%RH。檢(jian)(jian)(jian)定(ding)(ding)(ding)箱溫(wen)度設定(ding)(ding)(ding)20℃。檢(jian)(jian)(jian)定(ding)(ding)(ding)箱達(da)到(dao)設定(ding)(ding)(ding)值后(hou)(hou),應(ying)穩定(ding)(ding)(ding)30min后(hou)(hou)開始讀(du)數(shu)(shu)(shu),先讀(du)標(biao)準器(qi)(qi),后(hou)(hou)讀(du)被(bei)檢(jian)(jian)(jian)儀器(qi)(qi),間隔5min后(hou)(hou)再(zai)讀(du)一次。取兩次的(de)(de)(de)(de)算數(shu)(shu)(shu)平均值作為標(biao)準器(qi)(qi)示(shi)值和被(bei)檢(jian)(jian)(jian)儀器(qi)(qi)的(de)(de)(de)(de)溫(wen)度示(shi)值。
濕溫度計機械準還是電子準
要看精度等級如何,一般來說精度等級越高的測量結果越準確。并不意味著機械濕度計就沒有電子的準。
濕溫度計原理
一(yi)般來說濕度計原理都比較簡單,電子的基本(ben)是(shi)通過電子元件(jian)感受外界濕度和溫度的變(bian)化然后顯示(shi)相應數字(zi);機械的則根據(ju)種類不同略有(you)區別。
家用溫濕度計如何選擇
1、選擇測量(liang)精(jing)度。
2、選擇測量范圍。
3、考慮(lv)時漂(piao)和溫漂(piao)。
4、選擇溫濕度計品牌產品。
溫濕度計怎么看濕度
讀(du)溫(wen)度(du)(du)(du)(du)(du)計(ji)的溫(wen)度(du)(du)(du)(du)(du),溫(wen)度(du)(du)(du)(du)(du)計(ji)的溫(wen)度(du)(du)(du)(du)(du)向(xiang)上是(shi)變(bian)大的,每(mei)小(xiao)格(ge)0.5C°。從刻(ke)度(du)(du)(du)(du)(du)盤下方讀(du)出相(xiang)對(dui)濕度(du)(du)(du)(du)(du)。相(xiang)對(dui)濕度(du)(du)(du)(du)(du)從左(zuo)往(wang)右(you)是(shi)變(bian)小(xiao)的,每(mei)小(xiao)格(ge)是(shi)2%。濕度(du)(du)(du)(du)(du)計(ji)顯示的并非度(du)(du)(du)(du)(du)數(shu)而是(shi)百分(fen)比,正常生(sheng)活的室(shi)內濕度(du)(du)(du)(du)(du)應保持在45%-70%左(zuo)右(you)。
