甲醇檢測管****11TP
甲醇檢測管CH3OH****11TP ，GASTEC 甲醇檢測管CH3OH****11TP氣體檢測管，日本GASTEC 甲醇檢測管CH3OH****11TP電泵用氣體檢測管檢測范圍20-300ppm。
GASTEC為了滿足用戶在氣體檢測方面的需要，而開發(fā)出了電子自動采氣泵。用傳統(tǒng)的電子吸氣泵幾乎不能進行有效的采氣，因為檢測管里的填充試劑密度很高。而GASTEC開發(fā)的GSP電泵系列能提供強勁吸力，能滿足特定的檢測管的取樣要求。電泵和檢測管組成的新的檢測系統(tǒng)能適用于作業(yè)環(huán)境的檢測。 甲醇檢測管CH3OH****11TP ，GASTEC 甲醇檢測管CH3OH****11TP氣體檢測管，日本GASTEC 甲醇檢測管CH3OH****11TP電泵用氣體檢測管檢測范圍20-300ppm。
