简单介绍
苯检测管NO.122PP，GASTEC苯检测管NO.122PP检测管，GASTEC苯检测管C6H6NO.122P电泵用气体检测管检测范围250-3000μg/m3。
苯检测管NO.122PP的详细介绍
苯检测管NO.122PP
苯检测管NO.122PP，GASTEC苯检测管NO.122PP检测管，GASTEC苯检测管C6H6NO.122P电泵用气体检测管检测范围250-3000μg/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。
