磷化氢PH3有毒气体检测管121SS PHOSPHINE 200-6000ppm

简要描述:

磷化氢PH3有毒气体检测管121SS PHOSPHINE 200-6000ppm,有限/密闭空间气体安全检测箱,有限空间应急防护箱,AP-20通过直接读取方式,可简单测定空气中各种气体的浓度。使用1个检测器(泵),只要更换检测管,就能进行测定。由于是直接读取式,所以不会出现人为误差。1冲程(100ml)30~120秒,就可以结束浓度测定。体育与休闲:游泳池、训练场、室内体育设施等,环境:环保局、疾病预防控制中心、环境监测站(大队)等,突发性化学事故:如火灾、爆炸、毒气泄漏等,针对突发公共卫生事件

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.
