美國(guó)BIOS公司低流量校準(zhǔn)器 Defender 520L 5-500ml/min

流量校準(zhǔn)器Defender 510/520 儀器介紹：

Defender 510/520是新一代的干式氣體流量計(jì)，它是一級(jí)流量計(jì),，并被眾多的個(gè)體采樣泵廠商推薦和配套使用,。可用于工業(yè)衛(wèi)生,、環(huán)保領(lǐng)域和各類實(shí)驗(yàn)室,。它采用干式活塞運(yùn)動(dòng)的原理，一次按鍵即可產(chǎn)生連續(xù)多個(gè)讀數(shù)。與傳統(tǒng)的泡沫式流量計(jì)相比,，使用更加方便快速,。520型號(hào)比510增加了同時(shí)測(cè)試溫度和壓力的功能。

流量校準(zhǔn)器Defender 510/520 主要特點(diǎn)：

采用干式活塞原理,，使用簡(jiǎn)單方便
流量精確控制,，經(jīng)過(guò)ISO17025認(rèn)證
結(jié)構(gòu)緊湊
寬大顯示屏幕
每組讀數(shù)高達(dá)100個(gè)
可內(nèi)置溫度、壓力傳感器,，優(yōu)化測(cè)試結(jié)果（520系列）
