一氧化碳報警器供應

一(yi)氧(yang)(yang)化(hua)(hua)(hua)碳(tan)報(bao)(bao)警(jing)器(qi)(qi)是(shi)通過(guo)一(yi)氧(yang)(yang)化(hua)(hua)(hua)碳(tan)傳(chuan)(chuan)感器(qi)(qi)感應(ying)空氣(qi)中一(yi)氧(yang)(yang)化(hua)(hua)(hua)碳(tan)氣(qi)體的(de)(de)濃度(du)(du)(du)轉變成電(dian)信號(hao)，電(dian)信號(hao)的(de)(de)大小跟一(yi)氧(yang)(yang)化(hua)(hua)(hua)碳(tan)的(de)(de)濃度(du)(du)(du)有關。一(yi)氧(yang)(yang)化(hua)(hua)(hua)碳(tan)報(bao)(bao)警(jing)器(qi)(qi)按所(suo)使用的(de)(de)傳(chuan)(chuan)感器(qi)(qi)來分類，一(yi)般(ban)分為半導體一(yi)氧(yang)(yang)化(hua)(hua)(hua)碳(tan)報(bao)(bao)警(jing)器(qi)(qi)、電(dian)化(hua)(hua)(hua)學一(yi)氧(yang)(yang)化(hua)(hua)(hua)碳(tan)報(bao)(bao)警(jing)器(qi)(qi)、紅外一(yi)氧(yang)(yang)化(hua)(hua)(hua)碳(tan)檢測(ce)儀等，從測(ce)量靈敏(min)度(du)(du)(du)、精度(du)(du)(du)、穩定性(xing)、抗交叉氣(qi)體干(gan)擾來說，性(xing)能較好的(de)(de)是(shi)紅外一(yi)氧(yang)(yang)化(hua)(hua)(hua)碳(tan)檢測(ce)儀，但比較昂貴(gui)適(shi)合實(shi)驗室使用，民(min)用的(de)(de)一(yi)般(ban)為半導體和(he)電(dian)化(hua)(hua)(hua)學的(de)(de)一(yi)氧(yang)(yang)化(hua)(hua)(hua)碳(tan)報(bao)(bao)警(jing)器(qi)(qi)。

半導(dao)(dao)體一氧(yang)化(hua)碳報警器采用半導(dao)(dao)體型一氧(yang)化(hua)碳傳感(gan)器作為敏感(gan)元(yuan)件，要(yao)求其(qi)敏感(gan)元(yuan)件恒(heng)溫(wen)(wen)在200℃左右時能快速響應，因此要(yao)給(gei)其(qi)增加(jia)電熱(re)絲加(jia)熱(re)，所以要(yao)提供比(bi)較大的電流，當溫(wen)(wen)度、濕度甚至風變(bian)化(hua)大對其(qi)精確測量很(hen)不利，還(huan)有就是容易受(shou)到(dao)其(qi)它氣(qi)體的交叉干擾，如酒精、氮(dan)氧(yang)化(hua)物、氫(qing)氣(qi)、烷類等氣(qi)體的干擾，容易誤報，但其(qi)價廉。一般使(shi)用壽(shou)命(ming)可達五(wu)年。

電(dian)(dian)(dian)(dian)(dian)化(hua)(hua)學一氧(yang)(yang)化(hua)(hua)碳報警器(qi)(qi)采用零功耗電(dian)(dian)(dian)(dian)(dian)化(hua)(hua)學一氧(yang)(yang)化(hua)(hua)碳傳(chuan)感器(qi)(qi)作為(wei)敏(min)(min)感元(yuan)件，大都(dou)采用電(dian)(dian)(dian)(dian)(dian)化(hua)(hua)學法中(zhong)的(de)(de)(de)定(ding)電(dian)(dian)(dian)(dian)(dian)位電(dian)(dian)(dian)(dian)(dian)解法原理，利用定(ding)電(dian)(dian)(dian)(dian)(dian)位電(dian)(dian)(dian)(dian)(dian)解法進行氧(yang)(yang)化(hua)(hua)還(huan)原電(dian)(dian)(dian)(dian)(dian)化(hua)(hua)學反(fan)應，檢測擴散電(dian)(dian)(dian)(dian)(dian)流便(bian)可(ke)得(de)出一氧(yang)(yang)化(hua)(hua)碳氣(qi)(qi)體的(de)(de)(de)濃(nong)度(du)，并且有很好的(de)(de)(de)線性(xing)測量(liang)范圍以(yi)及很高的(de)(de)(de)選擇性(xing)，抗(kang)交叉氣(qi)(qi)體干擾能力也(ye)很強，價格相(xiang)對(dui)比較(jiao)貴。電(dian)(dian)(dian)(dian)(dian)化(hua)(hua)學一氧(yang)(yang)化(hua)(hua)碳傳(chuan)感器(qi)(qi)為(wei)零功耗型，無需加熱(re)，非常(chang)適合(he)配合(he)低功耗的(de)(de)(de)檢測電(dian)(dian)(dian)(dian)(dian)路采用電(dian)(dian)(dian)(dian)(dian)池供電(dian)(dian)(dian)(dian)(dian)，做成一氧(yang)(yang)化(hua)(hua)碳濃(nong)度(du)表、便(bian)攜式一氧(yang)(yang)化(hua)(hua)碳報警器(qi)(qi)等。電(dian)(dian)(dian)(dian)(dian)化(hua)(hua)學一氧(yang)(yang)化(hua)(hua)碳傳(chuan)感器(qi)(qi)長(chang)期暴露在(zai)無氧(yang)(yang)氣(qi)(qi)體樣品、酒精(jing)、油(you)漆等刺(ci)激性(xing)溶劑(ji)中(zhong)會(hui)影(ying)響其靈敏(min)(min)度(du)和壽命(ming)，甚至(zhi)會(hui)失效。電(dian)(dian)(dian)(dian)(dian)化(hua)(hua)學一氧(yang)(yang)化(hua)(hua)碳傳(chuan)感器(qi)(qi)在(zai)空氣(qi)(qi)中(zhong)的(de)(de)(de)使用一般為(wei)三年(nian)，也(ye)有五(wu)年(nian)的(de)(de)(de)，更長(chang)的(de)(de)(de)可(ke)達八年(nian)以(yi)上。
