甲醇检测管****11TP
甲醇检测管CH3OH****11TP ，GASTEC 甲醇检测管CH3OH****11TP气体检测管，日本GASTEC 甲醇检测管CH3OH****11TP电泵用气体检测管检测范围20-300ppm。
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。 甲醇检测管CH3OH****11TP ，GASTEC 甲醇检测管CH3OH****11TP气体检测管，日本GASTEC 甲醇检测管CH3OH****11TP电泵用气体检测管检测范围20-300ppm。
