日本KITAGAWA北川式甲乙酮CH3COC2H5氣體檢測管122SA 0.05-5.0%

簡(jiǎn)要描述:

日本KITAGAWA北川式甲乙酮CH3COC2H5氣體檢測管122SA METHYL ETHYL KETONE 0.05-5.0%,氣體檢測管使用安全。使用時(shí)手動(dòng)操作,無(wú)需要電源、熱源,在有易燃易爆氣體存在的場(chǎng)所能安全使用。價(jià)格低廉、攜帶方便。該產(chǎn)品雖然是一次性使用,但與其它化學(xué)和儀器方法測量的總價(jià)格比起來(lái),還是便宜,而且又不需要維護修理,則更顯得低廉。檢測管體積小,重量輕,便于操作人員在各種環(huán)境下使用。
