HM-3A通風(fēng)干濕表、電動(dòng)通風(fēng)干濕表簡(jiǎn)介，通風(fēng)干濕表，HM-3A型電動(dòng)通風(fēng)干濕表，電動(dòng)通風(fēng)干濕表生產(chǎn)廠家，電動(dòng)通風(fēng)干濕表價(jià)格
通風(fēng)干濕表、電動(dòng)通風(fēng)干濕表由兩只相同的***溫度表和一個(gè)通風(fēng)器組成，結(jié)構(gòu)簡(jiǎn)單，工藝性強(qiáng)。、，它主要適用于氣象臺(tái)站、工礦企業(yè)、實(shí)驗(yàn)室及研究單位等測(cè)量空氣溫度及相對(duì)濕度之用，是測(cè)量溫度和濕度的二等測(cè)量標(biāo)準(zhǔn)。通風(fēng)干濕表、電動(dòng)通風(fēng)干濕表.

一、電動(dòng)通風(fēng)干濕表參數(shù)：
1、名稱：通風(fēng)干濕表、電動(dòng)通風(fēng)干濕表
2、型號(hào)：HM-3A
3、溫度測(cè)量范圍：-25℃～+50℃ 或 -35℃～+45℃
4、小分度：0.2℃
5、濕度測(cè)量范圍：10%RH～100%RH

6、通風(fēng)速度：電動(dòng)通風(fēng)3m/s以上
7、工作電壓： AC：220V/50或者DC：9V/1A直流電源
8、尺寸：φ90mm～418mm
9、重量：1.1kg
10、電動(dòng)通風(fēng)干濕表用途：電動(dòng)通風(fēng)干濕表用于氣象臺(tái)站、工礦企業(yè)、實(shí)驗(yàn)室及研究單位等測(cè)量空氣溫度及相對(duì)濕度之用，其他測(cè)量時(shí)作標(biāo)準(zhǔn)儀器。隆拓牌電動(dòng)通風(fēng)干濕表特點(diǎn)就是通風(fēng)速度穩(wěn)定，測(cè)定誤差小，使用方便。
二、電動(dòng)通風(fēng)干濕表原理：
電動(dòng)通風(fēng)干濕表工作原理就是電機(jī)帶動(dòng)風(fēng)扇轉(zhuǎn)動(dòng)后給予***速度的空氣流，流經(jīng)兩支并排的溫度表，其中一支的***球部纏以浸濕的脫脂紗布。由于紗布上水分的蒸發(fā)而使該溫度表的溫度下降，對(duì)比兩支溫度表（浸濕與未浸濕）的溫度差，經(jīng)查表換算可求出空氣的相對(duì)濕度、濕度等。通風(fēng)干濕表、電動(dòng)通風(fēng)干濕表
