氣體流量計/ 流量校準器Defender 510/520/530 儀器介紹:
Defender 510/520/530是新一代的干式氣體流量計,它是一級流量計,并被眾多的個體采樣泵廠商推薦和配套使用。可用于工業衛生、環保領域和各類實驗室。它采用干式活塞運動的原理,一次按鍵即可產生連續多個讀數。與傳統的泡沫式流量計相比,使用更加方便快速。520型號比510增加了同時測試溫度和壓力的功能。
流量校準器Defender 510/520/530 主要特點:
采用干式活塞原理,使用簡單方便
流量精確控制,經過ISO17025認證
結構緊湊
寬大顯示屏幕
每組讀數高達100個
可內置溫度、壓力傳感器,優化測試結果(520系列)
