磷化氫PH3有毒氣體檢測(cè)管121SS PHOSPHINE 200-6000ppm

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.
