产品描述
p-二氯苯检测管****27P
p-二氯苯检测管****27P，GASTECp-二氯苯检测管 ****27P气体检测管，GASTECp-二氯苯检测管 ****27P电泵用气体检测管检测范围100-3000μg/m3。
GASTEC为了满足用户在气体检测方面的需要，而开发出了电子自动采气泵。用传统的电子吸气泵几乎不能进行有效的采气，因为检测管里的填充试剂密度很高。而GASTEC开发的GSP电泵系列能提供强劲吸力，能满足特定的检测管的取样要求。电泵和检测管组成的新的检测系统能适用于作业环境的检测。

Miscellaneous
Electric sampling pump
This detector tube is suited for measuring p-dichlorobenzene in indoor environments. The GSP-200 / GSP-300FT-2 series automatic gas samplers (or comparable sampling devices/pumps) should always be used for optimal performance.
A deviation of +/-10% in the sampling flowrate (i.e. amount of air flowing through the tube at a given moment) or the sampling amount (total sampled amount of target substance) causes an average margin of error of approx. +/-10% (maximum +/-20%) in the indicated value. |
