用途：MO-200氧气测量仪可(ke)用(yong)(yong)于室(shi)内氧(yang)(yang)气(qi)(qi)(qi)(qi)测(ce)(ce)量(liang)，气(qi)(qi)(qi)(qi)候室(shi)氧(yang)(yang)气(qi)(qi)(qi)(qi)监(jian)(jian)测(ce)(ce)，堆肥、尾矿氧(yang)(yang)气(qi)(qi)(qi)(qi)监(jian)(jian)测(ce)(ce)，监(jian)(jian)测(ce)(ce)土壤(rang)(rang)(rang)氧(yang)(yang)化(hua)还原电(dian)(dian)位(wei)，以及在密闭空间中(zhong)监(jian)(jian)测(ce)(ce)土壤(rang)(rang)(rang)呼(hu)吸(xi)速率和土壤(rang)(rang)(rang)呼(hu)吸(xi)耗(hao)氧(yang)(yang)量(liang)，还可(ke)监(jian)(jian)测(ce)(ce)管线氧(yang)(yang)气(qi)(qi)(qi)(qi)浓度，MO200氧(yang)(yang)气(qi)(qi)(qi)(qi)测(ce)(ce)量(liang)仪由读数表和传感器组成。电(dian)(dian)流(liu)(liu)型的(de)氧(yang)(yang)气(qi)(qi)(qi)(qi)传感器包含一(yi)(yi)个铅正(zheng)极、金负(fu)极、电(dian)(dian)解液和一(yi)(yi)个Teflon膜。电(dian)(dian)极间的(de)电(dian)(dian)流(liu)(liu)与测(ce)(ce)量(liang)得到的(de)氧(yang)(yang)气(qi)(qi)(qi)(qi)浓度程(cheng)正(zheng)比，一(yi)(yi)个内置的(de)桥式电(dian)(dian)阻用(yong)(yong)于提供电(dian)(dian)压(ya)输出。作为电(dian)(dian)流(liu)(liu)型传感器，需(xu)要(yao)消耗(hao)少量(liang)氧(yang)(yang)气(qi)(qi)(qi)(qi)以产生响(xiang)应的(de)电(dian)(dian)压(ya)信(xin)号。当(dang)氧(yang)(yang)气(qi)(qi)(qi)(qi)浓度是20.95% (3240 mmol，23℃) 的(de)时候，测(ce)(ce)量(liang)得到的(de)氧(yang)(yang)气(qi)(qi)(qi)(qi)消耗(hao)是2.2 umol O2/天(tian)。电(dian)(dian)压(ya)信(xin)号输出响(xiang)应于空气(qi)(qi)(qi)(qi)氧(yang)(yang)气(qi)(qi)(qi)(qi)分压(ya)，分压(ya)标准单(dan)(dan)位(wei)是kPa，这些单(dan)(dan)位(wei)可(ke)以转换(huan)为%O2或ppm，大(da)气(qi)(qi)(qi)(qi)中(zhong)的(de)氧(yang)(yang)气(qi)(qi)(qi)(qi)浓度是大(da)约(yue)20.95%。

MO-200氧气测量仪特点：        

传(chuan)(chuan)感(gan)器(qi)配备(bei)加(jia)热(re)(re)检测器(qi)，传(chuan)(chuan)感(gan)器(qi)的前面的保(bao)护膜(mo)可(ke)以(yi)被加(jia)热(re)(re)，当传(chuan)(chuan)感(gan)器(qi)在(zai)土壤或堆肥时可(ke)以(yi)防止水凝结阻挡扩散路径(jing)。        

坚(jian)固的(de)传感(gan)器外壳，即使酸性环境下也可使用(yong)(yong)，A0-001可用(yong)(yong)于扩散(san)式测(ce)量，A0-002可用(yong)(yong)于管线式测(ce)量。每个(ge)氧(yang)气传感(gan)器都内(nei)置一个(ge)温度(du)传感(gan)器，可实(shi)现温度(du)的(de)监测(ce)和(he)，信号校正(zheng)
