style="text-indent:25px">氣體檢測儀壽命：氣體檢測儀的使用壽命主要取決于，它的主要元件-----傳感器。我們也知道，不可能有一種傳感器可以檢測所有的氣體，滿足所有的要求，各種氣體和各種環(huán)境使用的傳感器也不一樣，大致可以分為:用于檢測有毒氣體濃度的傳感器和用于檢測可燃?xì)怏w的濃度的傳感器。用于測量有毒氣體濃度的傳感器大多是電化學(xué)傳感器，它是基于電化學(xué)原理工作的傳感器，影響其壽命的主要是電解液，一般的傳感器在2~3年之后，電解液就消耗的不能再正常工作了，所以電化學(xué)傳感器的使用壽命是2~3年。用于檢測可燃?xì)怏w濃度的傳感器大多是催化燃燒傳感器，它的使用壽命在3~5年。用于檢測氣體流量的是熱導(dǎo)式氣體分析儀。舟山礦山便攜式氣體檢測儀多少錢</p><p

style="text-indent:25px">氣體檢測儀選購方法：確定使用場合:工業(yè)環(huán)境的不同，選擇氣體檢測儀種類也不同。按使用方式可分為臺式氣體檢測儀和手持氣體檢測儀。按可檢測的氣體數(shù)量可分為單一氣體檢測儀和多種氣體檢測儀。按氣體傳感器的原理可分為紅外線氣體檢測儀、熱磁氣體檢測儀、電化學(xué)式氣體檢測儀、半導(dǎo)體式氣體檢測儀、紫外線氣體檢測儀等復(fù)合式氣體檢測儀：復(fù)合式多氣體檢測儀可以在一臺儀器上配備所需的多個氣體檢測傳感器，所以它具有體積小、重量輕、響應(yīng)快、同時多氣體濃度顯示的特點。更重要的是，弈揚復(fù)合式多氣體檢測儀的價格要比多個單一擴散式氣體檢測儀便宜一些，使用起來也更加方便。需要注意的是在選擇這類檢測儀時，較好選擇具有單獨開關(guān)各個傳感器功能的儀器，以防止由于一個傳感器損害影響其它傳感器使用。南通二氧化碳?xì)怏w檢測儀</p><p
