一氧化碳CO氣體檢知管106B CARBON MONOXIDE 10-1000ppm

Tube 06B
1. PERFORMANCE
1） Measuring range ：10-1,000 ppm
This tube is calibrated based on the sampling time not related with number
of pump strokes.
2） Sampling time ：0.5-5.0 minutes
3） Detectable limit ：10 ppm（5.0 minutes）
4） Shelf life ：3 years
5） Operating temperature ：0～40℃
6） Temperature compensation ：Necessary（See "TEMPERATURE CORRECTION TABLE）
7） Reading ：Colour intensity method using colour standard chart shown in below
8） Colour change ：Pale yellow→Green to Blue
2. RELATIVE STANDARD DEVIATION
RSD-low：　　　RSD-mid.：　　　RSD-high：
3. CHEMICAL REACTION
Molybdate is reduced and molybdeum blue is produced.
CO＋PdSO4＋（NH4）MoO4→Mo3O8
4. CALIBRATION OF THE TUBE
STANDARD GAS CYLINDER METHOD
5. INTERFERENCE AND CROSS SENSITIVITY

CARBON MONOXIDE
Substance Interference ppm Coexistence
Nitrogen dioxide 1 Lower readings are given.
Hydrogen sulphide Black stain is produced. 1,000 Black stain is produced and higher
readings are given.
Hydrogen（over 40℃） Similar stain is produced 10％ Whole reagent is discoloured to
Blue and higher readings are given.
6. NOTE
1）In case of determining CO concentration,it is necessary to take a waiting time related to the sampling time
andambient tenperature.After thewaiting time,compare the second section of reagent with the colour standard
chart.
2）In case of spontaneous conbustion of coal mines,Ethylene and CO are produced.The first section is partially
stained to deep blue from the top of the section according tc Ethylene concentration .Whole areas of first
and second sectionsare equallystained to greenishblue according to CO concentration.The first sectionis
available to detect less 5 ppm of Ethylene.
