气(qi)(qi)(qi)(qi)(qi)体(ti)(ti)检(jian)(jian)(jian)(jian)测(ce)(ce)(ce)仪(yi)是(shi)一(yi)种气(qi)(qi)(qi)(qi)(qi)体(ti)(ti)泄露(lu)浓度(du)检(jian)(jian)(jian)(jian)测(ce)(ce)(ce)的(de)仪(yi)器仪(yi)表工具,其中(zhong)包括(kuo):便携式(shi)气(qi)(qi)(qi)(qi)(qi)体(ti)(ti)检(jian)(jian)(jian)(jian)测(ce)(ce)(ce)仪(yi)、手持式(shi)气(qi)(qi)(qi)(qi)(qi)体(ti)(ti)检(jian)(jian)(jian)(jian)测(ce)(ce)(ce)仪(yi)、固(gu)定(ding)式(shi)气(qi)(qi)(qi)(qi)(qi)体(ti)(ti)检(jian)(jian)(jian)(jian)测(ce)(ce)(ce)仪(yi)、在线(xian)式(shi)气(qi)(qi)(qi)(qi)(qi)体(ti)(ti)检(jian)(jian)(jian)(jian)测(ce)(ce)(ce)仪(yi)等。主(zhu)要利用气(qi)(qi)(qi)(qi)(qi)体(ti)(ti)传(chuan)感(gan)器来检(jian)(jian)(jian)(jian)测(ce)(ce)(ce)环境(jing)中(zhong)存在的(de)气(qi)(qi)(qi)(qi)(qi)体(ti)(ti)种类(lei),气(qi)(qi)(qi)(qi)(qi)体(ti)(ti)传(chuan)感(gan)器是(shi)用来检(jian)(jian)(jian)(jian)测(ce)(ce)(ce)气(qi)(qi)(qi)(qi)(qi)体(ti)(ti)的(de)成(cheng)份和含量的(de)传(chuan)感(gan)器。

一般(ban)认为,气(qi)(qi)体(ti)(ti)(ti)传(chuan)(chuan)感器的(de)定义(yi)是(shi)以检(jian)测(ce)目标为分类基础的(de),也就(jiu)是(shi)说,凡是(shi)用(yong)于检(jian)测(ce)气(qi)(qi)体(ti)(ti)(ti)成份和(he)浓度的(de)传(chuan)(chuan)感器都称作(zuo)气(qi)(qi)体(ti)(ti)(ti)传(chuan)(chuan)感器,不管它(ta)是(shi)用(yong)物理方(fang)法(fa),还是(shi)用(yong)化学方(fang)法(fa)。比(bi)如,检(jian)测(ce)气(qi)(qi)体(ti)(ti)(ti)流量的(de)传(chuan)(chuan)感器不被看作(zuo)气(qi)(qi)体(ti)(ti)(ti)传(chuan)(chuan)感器,但是(shi)热导(dao)式气(qi)(qi)体(ti)(ti)(ti)分析仪却属于重要的(de)气(qi)(qi)体(ti)(ti)(ti)传(chuan)(chuan)感器,尽管它(ta)们有时使(shi)用(yong)大体(ti)(ti)(ti)一致的(de)检(jian)测(ce)原理。
