數(shù)字流量校準(zhǔn)器Defender 520H 300-30000ml/min 為了精確測量通過采樣介質(zhì)的空氣體積,空氣采樣儀器必須調(diào)節(jié)流量、校準(zhǔn)和定期檢查,以保證流量的準(zhǔn)確。實踐表明,個人采樣泵在每次使用之前、之后都必須校準(zhǔn),并在使用過程中定期檢查。微電腦大流量校準(zhǔn)器,大、中、小流量校準(zhǔn)器,本儀器小巧美觀,可攜帶到現(xiàn)場對各種氣體采樣儀器進行流量校準(zhǔn)。

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,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(yè)衛(wèi)生、環(huán)保領(lǐng)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(chǎn)生連續(xù)多個讀數(shù)。與傳統(tǒng)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。
