                      戊胺CH3(CH2)3CH2NH2氣體檢測(cè)管105SD PENTYL AMINE 2-22ppm

                      簡(jiǎn)要描述:

                      戊胺CH3(CH2)3CH2NH2氣體檢測(cè)管105SD PENTYL AMINE 2-22ppm,通過(guò)直接讀取方式,可簡(jiǎn)單測(cè)定空氣中各種氣體的濃度。使用1個(gè)檢測(cè)器(泵),只要更換檢測(cè)管,就能進(jìn)行測(cè)定。由于是直接讀取式,所以不會(huì)出現(xiàn)人為誤差。1沖程(100ml)30~120秒,就可以結(jié)束濃度測(cè)定。

                      Amines Similar stain is produced. Higher readings are given.
                      (NOTE)
                      When the concentration is below 1 ppm, 2 to 5 pump strokes can be used to detemine the lower concentration.
                      Following formula is available for actual concentration.
                      Actual concentration=Reading value× 1

                      The KITAGAWA Gas Detector Tube System is a complete sampling and analysis system for determining hazardous gas and vapour concentrations quickly and easily. The KITAGAWA Gas Detector Tube System is comprised of an Air Sampling Pump and Precision Gas Detector Tubes.

                      The KITAGAWA air sampling pump reproducibly draws 100cc of sample air through the detector tube. All detector tubes are calibrated for a single pump stroke; there is no need for multiple volumes or stroke counters.

                      Each detector tube is formulated with high purity reagents that absorb and react with the target gas or vapour being measured. A colorimetric stain is created that is proportional in length to the concentration. For most tubes, the concentration is read directly off the measurement scale on each tube. 
                       How To Use The KITAGAWA Gas Detector Tube System 
                       
                      Detector tubes are available to measure more than 200 different kinds of gases and vapours. For many gases and vapours, there are several concentration ranges available giving you the flexibility to measure both low and high concentrations without sacrificing precision.

                      For specific information, please refer to the list of detector tubes.
