进口二氧化硫SO2气体检测管103SE SULPHUR DIOXIDE 0.25-10ppm

简要描述:

进口二氧化硫SO2气体检测管103SE SULPHUR DIOXIDE 0.25-10ppm,【检知管法】(detectortubemethod)指用试剂浸泡过的载体颗粒装在玻璃管中,当被测空气以一定速度抽过此管时,被测物质与试剂发策颜色反应,然后根据颜色的深浅和色柱的长短,与标准色板或浓度标尺进行比较,从而作出定性和半定量的分析方法。所用载体应具亩下列性能:(1)化学惰性,即不与被测物质和试剂起反应;(2)质地牢固,并能粉碎成一定大小的颗粒;(3)白色多孔或表面粗糙的固体物质。常用的载体有硅胶

Nitrogen dioxide Pale pink stain is produced. 3 becomes un clear and higher
readings are given.
Hydrogen chloride 〃Higher readings are given.
(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
