低(di)濃(nong)度(du)恒溫(wen)恒濕(shi)稱重系統是武漢(han)安德信檢測設備(bei)有限公司根據新標(biao)準需(xu)求固(gu)定(ding)(ding)污(wu)染(ran)源(yuan)廢(fei)棄低(di)濃(nong)度(du)的(de)(de)測定(ding)(ding)標(biao)準研發的(de)(de)新設備(bei)，符合：《固(gu)定(ding)(ding)污(wu)染(ran)源(yuan)廢(fei)氣(qi)低(di)濃(nong)度(du)顆粒物的(de)(de)測定(ding)(ding)重量法》（HJ836-2017）。HJ836-2017《固(gu)定(ding)(ding)污(wu)染(ran)源(yuan)廢(fei)氣(qi)低(di)濃(nong)度(du)顆粒物的(de)(de)測定(ding)(ding)重量法》的(de)(de)檢測限：《固(gu)定(ding)(ding)污(wu)染(ran)源(yuan)中顆粒物測定(ding)(ding)與(yu)氣(qi)態(tai)污(wu)染(ran)物采樣方法》。

恒溫(wen)恒濕(shi)稱(cheng)(cheng)重系統是為滿足(zu)環(huan)保部新國標(biao)HJ836-2017《固定(ding)污染源低濃度(du)(du)度(du)(du)的(de)(de)測定(ding)重量(liang)法》中關于采樣(yang)(yang)(yang)后稱(cheng)(cheng)量(liang)條件的(de)(de)要(yao)(yao)求，在恒溫(wen)恒濕(shi)環(huan)境內放(fang)(fang)置高精度(du)(du)天平，將要(yao)(yao)稱(cheng)(cheng)量(liang)的(de)(de)樣(yang)(yang)(yang)品(pin)(pin)放(fang)(fang)入(ru)恒溫(wen)恒濕(shi)箱體內平衡(heng)24小時后再進行(xing)稱(cheng)(cheng)量(liang)。本產(chan)(chan)品(pin)(pin)解決(jue)了實驗(yan)室環(huan)境溫(wen)度(du)(du)濕(shi)度(du)(du)的(de)(de)變化對(dui)樣(yang)(yang)(yang)品(pin)(pin)稱(cheng)(cheng)重結(jie)果(guo)的(de)(de)影響(xiang)，極大的(de)(de)提高了稱(cheng)(cheng)量(liang)樣(yang)(yang)(yang)品(pin)(pin)結(jie)果(guo)的(de)(de)準確性，該產(chan)(chan)品(pin)(pin)也用于其它對(dui)稱(cheng)(cheng)量(liang)環(huan)境要(yao)(yao)求較(jiao)高的(de)(de)樣(yang)(yang)(yang)品(pin)(pin)稱(cheng)(cheng)量(liang)。
