CJJP型催化燃燒甲烷測定器檢定配套裝置

[用(yong)途]與空氣中甲(jia)烷標(biao)準氣體配套，用(yong)于檢(jian)定、校準便(bian)攜式甲(jia)烷檢(jian)測報警(jing)儀(yi)。

CJJP型催化燃燒甲烷測定器檢定配套裝置主要技術指標：

1 標準氣(qi)體(ti)輸入接口：5路輸入，可同時(shi)連接5種不同濃度標準氣(qi)體(ti)。

2 高(gao)壓(ya)（標準氣(qi)體）氣(qi)瓶減壓(ya)器：

  衡壓(ya)式氣體(ti)減壓(ya)器，二級減壓(ya)，衡壓(ya)輸出

  初級輸入壓力10～0.6MPa

  次級(ji)輸出壓(ya)力0.04～0.20MPa。

3 配(pei)套流量計：30～300ml/min 2.5級

4 外(wai)型(xing)尺寸：330×180×220（mm3）

CJJP型特點：

1. 減壓器

1.1 減壓(ya)器次級壓(ya)力(li)相對衡定，不需(xu)調節壓(ya)力(li)，減壓(ya)器使用壽命長。

1.2 在較寬的輸入(ru)壓(ya)力范圍內能保持輸出壓(ya)力的相對衡定。

1.3 減壓(ya)器在(zai)較低的輸(shu)(shu)入壓(ya)力下(xia)（輸(shu)(shu)入壓(ya)力＜1MPa時）仍能正(zheng)常工(gong)作，標準(zhun)氣體瓶中的標準(zhun)氣體能得到大利用，節(jie)約了(le)標氣的使用成本。

2 流(liu)量(liang)(liang)穩(wen)定，流(liu)量(liang)(liang)調節(jie)方(fang)便。通(tong)過調節(jie)減(jian)壓器輸出壓力端上的流(liu)量(liang)(liang)調節(jie)閥可(ke)方(fang)便地調節(jie)連接管(guan)路中(zhong)的氣體流(liu)量(liang)(liang)，并且流(liu)量(liang)(liang)可(ke)較(jiao)長時間地保持(chi)穩(wen)定，使(shi)用非常方(fang)便。

3 結構緊(jin)湊，操(cao)作簡單方(fang)便、具有較高的可靠性。
