气(qi)(qi)体(ti)(ti)(ti)检(jian)(jian)(jian)(jian)测(ce)(ce)仪(yi)是(shi)一种气(qi)(qi)体(ti)(ti)(ti)泄露浓(nong)度检(jian)(jian)(jian)(jian)测(ce)(ce)的(de)(de)仪(yi)器(qi)仪(yi)表工具,其中包括:便携式(shi)(shi)气(qi)(qi)体(ti)(ti)(ti)检(jian)(jian)(jian)(jian)测(ce)(ce)仪(yi)、手持式(shi)(shi)气(qi)(qi)体(ti)(ti)(ti)检(jian)(jian)(jian)(jian)测(ce)(ce)仪(yi)、固定式(shi)(shi)气(qi)(qi)体(ti)(ti)(ti)检(jian)(jian)(jian)(jian)测(ce)(ce)仪(yi)、在(zai)(zai)线(xian)式(shi)(shi)气(qi)(qi)体(ti)(ti)(ti)检(jian)(jian)(jian)(jian)测(ce)(ce)仪(yi)等。主要利用(yong)气(qi)(qi)体(ti)(ti)(ti)传(chuan)感(gan)器(qi)来检(jian)(jian)(jian)(jian)测(ce)(ce)环境中存在(zai)(zai)的(de)(de)气(qi)(qi)体(ti)(ti)(ti)种类,气(qi)(qi)体(ti)(ti)(ti)传(chuan)感(gan)器(qi)是(shi)用(yong)来检(jian)(jian)(jian)(jian)测(ce)(ce)气(qi)(qi)体(ti)(ti)(ti)的(de)(de)成份和含量的(de)(de)传(chuan)感(gan)器(qi)。

一(yi)般认为(wei),气体传(chuan)(chuan)(chuan)感(gan)(gan)器(qi)(qi)的(de)定(ding)义是(shi)以检(jian)(jian)测目标为(wei)分类(lei)基(ji)础(chu)的(de),也就是(shi)说,凡是(shi)用于检(jian)(jian)测气体成份和(he)浓度(du)的(de)传(chuan)(chuan)(chuan)感(gan)(gan)器(qi)(qi)都称作气体传(chuan)(chuan)(chuan)感(gan)(gan)器(qi)(qi),不(bu)(bu)管(guan)它(ta)是(shi)用物理方(fang)法(fa),还(hai)是(shi)用化学(xue)方(fang)法(fa)。比如,检(jian)(jian)测气体流量(liang)的(de)传(chuan)(chuan)(chuan)感(gan)(gan)器(qi)(qi)不(bu)(bu)被看作气体传(chuan)(chuan)(chuan)感(gan)(gan)器(qi)(qi),但是(shi)热导式气体分析仪(yi)却属于重要(yao)的(de)气体传(chuan)(chuan)(chuan)感(gan)(gan)器(qi)(qi),尽管(guan)它(ta)们有时使用大体一(yi)致的(de)检(jian)(jian)测原理。
