                      簡要描述:

                      進(jìn)口二氧化硫SO2氣體檢測管103SE SULPHUR DIOXIDE 0.25-10ppm,【檢知管法】(detectortubemethod)指用試劑浸泡過的載體顆粒裝在玻璃管中,當(dāng)被測空氣以一定速度抽過此管時,被測物質(zhì)與試劑發(fā)策顏色反應(yīng),然后根據(jù)顏色的深淺和色柱的長短,與標(biāo)準(zhǔn)色板或濃度標(biāo)尺進(jìn)行比較,從而作出定性和半定量的分析方法。所用載體應(yīng)具畝下列性能:(1)化學(xué)惰性,即不與被測物質(zhì)和試劑起反應(yīng);(2)質(zhì)地牢固,并能粉碎成一定大小的顆粒;(3)白色多孔或表面粗糙的固體物質(zhì)。常用的載體有硅膠

                      (NOTE)
                      1)This detector tube is affected by abmbient relative humidity,therefore,it is necessary to compensate the reading of
                      gas detector tube with the following formula and correction confficient table.
                      Actual concentration=Reading Value(ppm)×Correction Coefficient
                      2)In case of 2 pump strokes, following formula is available for actual concentration.
                      Actual concentration=1/2×Reading value corrected with above formula
