[恒溫恒濕試驗箱]恒溫恒濕試驗箱的用水須知(zhi)(zhi)知(zhi)(zhi)識

　　恒溫(wen)恒濕試驗箱(xiang)主(zhu)要用于對試驗對象，比如：橡膠、塑(su)料零部(bu)件等產品做高溫(wen)、低溫(wen)、濕熱以及(ji)三者任意結合和交替進行試驗。本文為大家(jia)講(jiang)解恒溫(wen)恒濕試驗箱(xiang)用水須知兩(liang)大點。

　　加濕(shi)器一般都有個水(shui)(shui)位開關，水(shui)(shui)位開關的浮(fu)子(zi)中間(jian)為磁力棒，浮(fu)子(zi)不(bu)是仿氧(yang)化(hua)材料做的。所(suo)以時間(jian)一久(jiu)，或者(zhe)經(jing)常不(bu)換水(shui)(shui)會造(zao)成(cheng)水(shui)(shui)位開關短路(lu)，會造(zao)成(cheng)無法加濕(shi)或者(zhe)一直加濕(shi)的現象；

　　恒(heng)溫恒(heng)濕(shi)(shi)(shi)(shi)試(shi)驗箱(xiang)電(dian)阻(zu)率越大(da)說明水(shui)(shui)的(de)絕緣(yuan)性越好，（電(dian)阻(zu)率的(de)倒數就是(shi)電(dian)導率，電(dian)導率越小越好）那(nei)么(me)您用(yong)的(de)恒(heng)溫恒(heng)濕(shi)(shi)(shi)(shi)箱(xiang)一般是(shi)用(yong)脈沖（聲波）加(jia)(jia)濕(shi)(shi)(shi)(shi)，而加(jia)(jia)濕(shi)(shi)(shi)(shi)介(jie)質是(shi)水(shui)(shui)。那(nei)為(wei)何用(yong)水(shui)(shui)加(jia)(jia)濕(shi)(shi)(shi)(shi)呢？因為(wei)用(yong)水(shui)(shui)加(jia)(jia)濕(shi)(shi)(shi)(shi)粒子比較大(da)，如果(guo)長(chang)時間對濕(shi)(shi)(shi)(shi)度(du)(du)有(you)要求，那(nei)么(me)對濕(shi)(shi)(shi)(shi)度(du)(du)傳感(gan)(gan)器的(de)使用(yong)壽命會(hui)有(you)影響，（濕(shi)(shi)(shi)(shi)度(du)(du)傳感(gan)(gan)器：一般分為(wei)電(dian)容傳感(gan)(gan)器、霍尼非爾傳感(gan)(gan)器但是(shi)它們(men)的(de)PCB板(ban)有(you)些線路沒有(you)用(yong)隔水(shui)(shui)材(cai)料(liao)或(huo)是(shi)防(fang)氧化材(cai)料(liao)做的(de)。如果(guo)水(shui)(shui)質差，會(hui)使濕(shi)(shi)(shi)(shi)度(du)(du)傳感(gan)(gan)器短路。

　　小貼士：

　　關于恒(heng)(heng)溫恒(heng)(heng)濕試(shi)驗箱(xiang)(xiang)的(de)用(yong)(yong)(yong)(yong)水(shui)(shui)(shui)(shui)狀(zhuang)況，恒(heng)(heng)溫恒(heng)(heng)濕試(shi)驗箱(xiang)(xiang)用(yong)(yong)(yong)(yong)一般自(zi)(zi)來(lai)水(shui)(shui)(shui)(shui)是(shi)可以的(de)。濕度效果可以達到(dao)，但(dan)如(ru)果長期用(yong)(yong)(yong)(yong)自(zi)(zi)來(lai)水(shui)(shui)(shui)(shui)做濕度用(yong)(yong)(yong)(yong)水(shui)(shui)(shui)(shui)，水(shui)(shui)(shui)(shui)管中(zhong)很容(rong)易生出水(shui)(shui)(shui)(shui)垢，而(er)且(qie)自(zi)(zi)來(lai)水(shui)(shui)(shui)(shui)中(zhong)的(de)雜質還會吸附到(dao)產品表面（因為自(zi)(zi)來(lai)水(shui)(shui)(shui)(shui)中(zhong)含有(you)礦物(wu)質，有(you)些礦物(wu)質有(you)腐蝕性(xing)，對(dui)設備的(de)保養不好(hao)），水(shui)(shui)(shui)(shui)箱(xiang)(xiang)也會不干凈(jing)，如(ru)果客戶有(you)條件，最好(hao)是(shi)使用(yong)(yong)(yong)(yong)純凈(jing)水(shui)(shui)(shui)(shui)或(huo)蒸餾水(shui)(shui)(shui)(shui)，因為恒(heng)(heng)溫恒(heng)(heng)濕箱(xiang)(xiang)中(zhong)是(shi)設有(you)回水(shui)(shui)(shui)(shui)再利用(yong)(yong)(yong)(yong)的(de)所以成本也不用(yong)(yong)(yong)(yong)消(xiao)耗(hao)太大，對(dui)水(shui)(shui)(shui)(shui)管、水(shui)(shui)(shui)(shui)箱(xiang)(xiang)、水(shui)(shui)(shui)(shui)路等都比較(jiao)好(hao)。當然，只要(yao)勤換(huan)、勤洗自(zi)(zi)然水(shui)(shui)(shui)(shui)也是(shi)OK的(de)。
